I was testing, some issues I found:
*Log in, go to left menu, then setting. Next if you click the plus button besides username (top of menu) the combo displays my user name 2 times
*When I'm connected by wifi but without internet, the pin screen doesn't appear and I can click and create new post.

Suggestions:
*Search results is shown alwys in dark skin mode
*In dark mode, inactive links like tabs maybe could have more contrast
*When a menu option is selected and I click again nothing happens, maybe if it was highlighted will be fine

I'll continue testing other features !
