The main topic list on a mobile phone looks a odd to me the way the buttons wrap around on the top nav.
In particular, having the ‘Create Topic’ button on its own line, when there is all that extra space next to categories seems wasteful, so I started off with this change when playing around:
Then I experimented with:
- eliminating the category dropdown
perhaps on mobile, with an unbound category list, it’d make more sense to have a click on the category badge take the user to the category page. If a subcategory is chosen, it could use this idea to hint the parent category, but only display the subcategory text.
- using a dropdown for the latest/new/unread stuff
since this list of options is under better control, it could be collapsed to a dropdown for mobile
Finally, now that all that space is saved, making those top nav buttons sticky would be do-able on mobile too without eating up half the screen:
