Other bugs that are present now and which I know about:

— “Show/hide pinned message”: crash on click
— “Recent actions” button in profile: no reaction
— Right click on an inactive account in the main menu: crash
— Folders: bug with premium limits

Visual flaws:
— Icons that are out of general style: scheduled messages, notifications (in the profile header), Kotatogram settings
— Offset bug for icons of manage buttons in the profile

Features that are being rebuilt from scratch:
— Rounding of avatars (is in test version currently)
— Compact chats

This is not an exhaustive list, this is just what I've remembered about. Plus, I'm planning new features, but this will be after I fix the old ones.
