The existing table of contents has various problems.
- It does not show for mobile devices. It only shows for tablet devices.
- As @phuedx points out the existing table of contents will show a lot of whitespace at the bottom of the section, rather than a visual indication that the TOC is there but momentarily disabled
- In tablet on articles with long infoboxes it can be hard to see (see figure 1)
The secondary actions which currently features the talk and categories buttons feels like it is becoming a bit of a dumping ground
To access them the user must also scroll to the bottom of the page.
Design (probably outdated)
In the footer include an icon for table of contents. Tapping the icon will open table of contents in an overlay.
