Is it possible to add an undo feature in Minerva skin? An editor created this meta:User:FR30799386/undo.js script which adds an undo button while previewing a diff on mobile. I've asked on Village Pump (technical) in English Wikipedia to make it a gadget. Is it possible to make it a part of Mediawiki since the Minerva skin lacks an undo feature?
Topic on Talk:Beta Features
Note that gadgets aren't loaded on mobile, so you're right, you'd need to do it as a feature. Beta Features is desktop-only, however.
Well StructuredDiscussion is a beta feature but it works on Minerva skin. Also how to add this script to Mediawiki to make it work globally? It is compatible with any wiki which can run using Minerva skin.
No, StructuredDiscussions is a regular feature; opting into it for your talk page is a Beta Feature, mostly for ease of user interface.
If you want to add a new feature to Minerva, you should post a Phabricator task suggesting it and explaining why users will get value from it.
I see. Thanks. I will wait until it becomes a gadget on en-wiki.
