Works great, after setting correct permissions (couldn't save any changes in the GUI) with chown user.users /home/user/.config/MohammadAG (run as root in Xterm).

Works while I'm using a browser too, which is handy for quickly jumping into Emails or Conversations (I use ShortcutD to change song via camera focus long press).

Issue I've found is in the snap below; the black bar appears below the buttons whilst in a browser window (not on the desktop). Probably because the media controls normally take up most of this space. I see you're aware of this MohammadAG.
