SanketDube Hey, thanks for putting this together! UX is important to us, so this kind of feedback is very valuable.
I'm curious as to what you think about the GH issue that @tolgaaaltas linked above (flarum/core867), it feels like that might address some of these issues. As discussed in the issue, adding stuff to the bottom is difficult because some browsers put their own navigation there.
That being said, I think a step for these issues would be bringing more elements out from dropdowns on mobile (e.g. search). I also think it might be sensible to replace the new discussion icon with a "register" logo as tolgaaaltas mentioned.
SanketDube After Signing In, some users stumbled at how to create a topic. It's just an icon on top right of screen, top areas of mobile screens are generally less accessible.
Currently the number of elements on mobile view directly visible is quite limited, so it's interesting that users are having difficulty finding it. Maybe a floating bubble in the bottom right corner of the screen would be more intuitive? But that might obstruct/cover some of the discussion list / posts, so I don't know if that trade off would be worth it.
SanketDube While responding to topics, the user has to scroll down to end of topic replies to create a response. This also may be forces users to at least have a glance at other replies?
The button for this is in the exact same place as the button for starting a new topic, so if a bubble replacement were to happen it'd probably cover this as well.
SanketDube Profile, Settings, Logout buttons are hid in Hamburger menu after the username is clicked. Lot of space below username is blank. May be those buttons could be displayed below username with indentation?
That's a good point, the session dropdown could be collapsed fully while in mobile view; even if extensions add stuff (like with fof/links), the user could still just scroll down.
Divider between two replies on topic thread page is faint. A boulder break line could help?
Mixed feelings; I feel like the liked indicators, like/reply button, and avatar of the next user help show separation. This is something I think might be better left to per-forum customizations with custom LESS, although I suppose we could include it in an "appearance customization" guide in docs?
SanketDube Some users felt the font size is small; I felt that too. I now have added additional CSS to increase font size.
Same as above, I feel like this is a point of preference. However, there are also accessibility concerns here: I'd be happy to see a community extension that allows users to select a font size they prefer.
SanketDube Sometime the bar with close, save and post reply button was hid beyond screen, the user had to scroll up to view those button.
This is a bug that will be fixed for the next release
SanketDube The save and 'post reply' button is at top right corner of the screen. Top areas of mobile screen are usually less accessible.
I'd argue that's a good place for them to be: most interactions with the composer will be keyboard typing and use of formatting buttons, so those feel like good candidates to be lower down.
tolgaaaltas I think the main issue is composter's position. It's on top of the page. Maybe composer's itself should open bottom of the page, not send and save buttons. Because you will use that elements only one time in composer. But formatting and text area using more than that buttons. And if composer sticked bottom of the page, buttons also has more accessibility.
I'm not sure how this would work though: the composer is at the top of the page because the bottom half (usually) is taken up by the keyboard. I'm hypothesizing here of course, but it feels like most formatting button use would happen while the keyboard is open; I personally haven't ever typed up a post, and then closed the keyboard to apply formatting.
