Community Wishlist Survey 2021/Mobile and apps/Table of contents anchoring

Random proposal ►◄ Mobile and apps The survey has concluded. Here are the results!

Table of contents anchoring

Problem: In mobile versions (and desktop versions), if you want to access the table of contents bar, it is quite hard.
Who would benefit: Readers.
Proposed solution: Implement a TOC quick access button at pages that have Table of Contents. This can be done across mobile and desktop, where if the TOC is inaccessable at page location (at desktop), a button appears, where when clicked, shows the table of contents as a popup box.
More comments: This have been achieved across various methods that hijack the magic word __TOC__ to be put into a <html> tag. However, this workaround requires user scripts, and is definitely not anything that can be called accessability. This should be considered as an accessability tool.

Will help many people. Maybe you could have a sidebar/dropdown like on the Wikipedia mobile app. Seemplez (talk) 12:21, 7 December 2020 (UTC)[reply]
Hey @1233: thanks for the proposal! Regarding the desktop part, this wish could be granted as a part of the Desktop Improvements project. Therefore, this part doesn't need to be voted upon. Would it be acceptable for you if I moved this wish to the Mobile and apps category? SGrabarczuk (WMF) (talk) 19:03, 7 December 2020 (UTC)[reply]

Sure, whatever if possible. (Also note: if it is at Desktop improvement, it seems possible to fill up the blank space at the right. --1233 （T / C） 02:08, 8 December 2020 (UTC)[reply]

very important. Do not forget to add, the function: value transfer. In the mobile version, the option does not exist, it is very lacking. Thanks, and at night if there are any disruptions, I translated using Google Translate. לבלוב (talk) 09:36, 10 December 2020 (UTC)[reply]
