Talk:Beta Features/Hovercards

About this board

The Hovercards beta feature solves the core problem of users opening multiple tabs to gain an understanding of a word in the context of the subject they are reading. Whenever a reader hovers over a link to another article, a short summary of the subject, including its graphical image, is provided to them so they can decide whether they need to visit that subject more fully before continuing the current subject.

Please give us feedback on your experience using this beta feature so we can change and improve it. Each language is welcome in this discussion!

You can read more about the feature here.

Preview images of maps with a position marker

Wurgl (talkcontribs)

The german wikipedia has very often maps of some area with a position marker, the map is created from some image and an overlay with the position marker that seems to be created magically from wikidata.

An example of such a map is de:Muro_Lucano

When a hovercards pops up, the position marker is not shown which is IMHO not very helpful. You can reproduce that hovercard in the first line of de:Liste_der_Bischöfe_von_Muro_Lucano.

Malyacko (talkcontribs)

When I go to and click on the map, I expect a page with a bigger version of the map with the position marker still displayed. But all I get is a map of a country without a position marker which is not very helpful. In my opinion that is the actual problem to solve, and not creating some workarounds in Hovercards/Page-Previews code.

So for embedded PDFs or DJVUs from books, a specific page is often used with the page= syntax. However, Hovercards just uses the first page. See en:The Waste Land for an example.

yoruba language is a kind of language that is being spoken in nigeria and the people that speak yoruba are called the yorubas, i will just like someone to work with me on how i can make the history of yoruba known and be studie in other country as a foreign language as english language is made known in all the world.

CKoerner (WMF) (talkcontribs)

@Dunremi, I'm afraid you've ended up in the wrong location. Perhaps someone on the Yoruba Wikipedia can help you. I'm marking this as resolved as it is not on-topic and wish you the best!

The fact that there are similar tools like this Page Previews feature shouldn't discourage our community from making ours. Having one official tool providing the best features in a simple way for everyone is a great idea which doesn't require installing browser extensions. Listing the other extensions and add-ons is useful because we can review their design and features to improve our version.

Quiddity (WMF) (talkcontribs)

Yup, that's exactly why I started/researched the list. To show how popular the idea was (proving we ought to implement something) and to glean good ideas/designs from. :-)

EoRdE6 (talkcontribs)

Think this means this feature really needs to be globally rolled out to non-registered users then... Maybe leave as an option for registered users though because some prefer third party gadgets like Popups on english that give you way more details (for editors)

Edwardj 123 (talkcontribs)
To EoRdE6: I definitely agree that this feature would good for everyone outside beta testing, particularly as it is a fairly popular tool made by others, however this shouldn't happen super soon because it still needs to be finalised (main problems fixed, features added). Also an option for users to disable it on their account could be a good idea but it would be better to make Page Previews/Hovercards have the popular features of other third party tools to persuade users to use our official tool.
EoRdE6 (talkcontribs)

My issue with that is that editors still have very different requirements to readers therefore a reader centric tool will never function for editors... Third party tools allow editors to view page history and editors and block logs and protection and tons more all from the pop-up. It's messy and ugly but for editors it's useful. Readers have no use for that information so I would support giving them this basic version that is currently available...

Edwardj 123 (talkcontribs)
To EoRdE6: I definitely see your point but we could still provide these editor only stats in Page Previews/Hovercards as opt-in features enabled on users' settings pages which would have the benefit of persuading some editors to use our tool instead of competitors ones to keep ours supported and popular.

I’m considering switching from Navpopups to Hovercards, so I had a look on what features I’d miss:

  • Section previews (phab:T65792)
  • Section previews when hovering a link in the TOC
  • Diff previews, especially from the watchlist (I’m reading my watchlist almost exclusively that way) and page histories
  • Because the image is so large and makes the text appear in different locations, it takes significantly longer to focus on the beginning of the preview text
  • An overview of the page history (on hovering a link in the preview box)
  • An overview of a user’s recent contributions (on hovering a link in the preview box)
  • "Previews" (actually, full content) of references (solved by Reference Tooltips, actually nicer than Navpopups)
  • The ability to "hover through" categories (especially on commons)
  • Getting further information (basicly the information template, Navpopups simply shows the template source code in this case) on files in categories (from files embedded in articles that might get annoying, but could maybe also be useful)
  • In the case of no lead paragraph… (as I’ve read over here) just preview whatever’s next?
  • Seeing where a redirect leads to
  • Seeing the first few entries of a disambig page

(thanks for fixing the shitty formating from this Flow thingy and the link to the overview phab ticket, kind strangers :-) )

If this were a regular talk page, I’d just say „feel free to add phab links to the list items“, but I’m not sure whether that’s possible in Flow… Anyway, I hope this feedback is helpful :-)

The popups don't appear on imagemaps, any idea why?

TheDJ (talkcontribs)

imagemaps are not normal links.

Hovercards for Wikipedia links on external pages

Jo5chp (talkcontribs)

Hi! First of all i think this feature is awesome and makes researching much more enjoyable!

Anyway, I was immediately wondering if it would be possible to extend this feature on external, non-wiki pages. For example by having a plugin script that people would then link in their website to enable this feature. Or any kind of external interface for the information included in the hovercard. Is anyone here involved in development and/or planning and knows if this might become reality?

Greetings, Jo (total wiki greenhorn) ;)

First of all, it appears unfortunate that - apparently - there was no (prominent) public announcement of this test on dewiki. How is the email response team (OTRS) supposed to respond to questions about a feature it doesn't even know is enabled? I hope we haven't missed some announcement, but those of us who discussed the matter have not noticed anything like that.

Second, I'm relaying the user's feedback to you: "I find the newly introduced PopUps extremely annoying, because they pop up at the slightest touch while scrolling through the article and cover the text I actually want to read. I prefer the previous behavior, where I click on blue links only if I want to read the corresponding articles."

CKoerner (WMF) (talkcontribs)

Thanks for the feedback Pajz. I'm assuming, and please correct me if I'm wrong, that the test you are referring to is the recent A/B test? I left a notice on the Technik/Werkstatt letting the German community know of the test. If there was better venue I could have used to alert folks, please do let me know. Sorry for the confusion.

Reply to "Feedback" (talkcontribs)

I noticed today that Hovercards were no longer appearing on English Wikipedia. When I went to check my preferences page, I could not find it listed in the Beta section (nor in the regular preferences tab, as far as I could tell). Is there any way I could get the hovercards back? It's one of my favorite features!

2001:A61:22F5:1F01:6267:20FF:FE09:9AA4 (talkcontribs)

Same here :-( as on the German WP.

TheDJ (talkcontribs)

It's a bug:

Hovercards are causing the title text of the image links in w:en:Template:NYCS SSI to be hidden. Would it be possible to show the tooltip as well as the hovercard?

Whatamidoing (WMF) (talkcontribs)

My guess is that showing tooltips would be hard (but perhaps I'm wrong).

That template appears to show a dot or diamond, and to be used to convey important information. Completely apart from the problem of relying on tooltips when Hovercards shows the linked template rather than the tooltip, have you talked to the w:en:WP:ACCESS editors about whether a small icon with a tooltip is the best way to present that information?

Whatamidoing (WMF) (talkcontribs)

This question has also made me wonder how Hovercards interacts with templates that are used to build tables.

Jc86035 (talkcontribs)

I don't think it's a very good way of presenting the information, but usually there's a legend describing what they mean, such as this one. Hoever, it gets confusing since it's difficult to remember what they mean (there are at least 18 options of monochrome circles and diamonds, with some symbols being reused). Is it possible to unhide the title= attribute only if the <a> contains an <img>?

How would interaction with table-building templates be different to normal behaviour on link hovers?

Whatamidoing (WMF) (talkcontribs)

I was surprised that hovering over an image in the table at w:en:Staten Island Railway#Main Line stations would link me to w:en:List of New York City Subway services#Time periods, so now I'm wondering what other odd behaviors might happen from some of these complicated templates.

Jc86035 (talkcontribs)

I think this template is an outlier, since this sort of link is usually discouraged by the Manual of Style (at least on enwiki), and most other transport systems don't have this sort of convoluted time period system. The Staten Island Railway has the same operator, rolling stock and fare as the New York City Subway, so it's not too unexpected.

CKoerner (WMF) (talkcontribs)

I just created a task for the alt text with links issue:

Should I create one for the second for tables generated by templates? I'm not sure I fully understand the problem there. :)

Jc86035 (talkcontribs)

I don't think the table thing is a software bug, more to do with confusing article structure.

Whatamidoing (WMF) (talkcontribs)

Chris, I don't think that you should file a second bug report. It might make a fun test case, but I don't think that there are any bugs there.
