Goals
Navigation Popups are a useful gadget and should be promoted to a site feature. Many users miss out on its utility because they are not aware of it, due to its poor discoverability in preferences.

Key Changes
Restyling it to enable easy reading. Currently the type size is small & the margins are tight. Create a consistent visual style with the article type treatment. Emphasize the lead images, so a user gets an idea of a term using both text and image. The action set in the gadget feels out of context., hence we need to validate which of those actions are useful for readers and editors. Include the last edited timestamp that we have tested on wikipedia mobile web, but de-emphasize it.

Implementation Plan
Reuse the text scraping and redirect ability of the Navigation popups. Scrape Low res versions of the lead images.
