The quick bar is a great addition to Home Assistant, and while there is room for improvement for the bar itself, my biggest issue is that I can’t use it easily in the mobile app or a touchscreen device because there is no keyboard to trigger it with the keyboard shortcut.
In my opinion, it should be possible to
a) optionally show an icon in the menu/ tab bar
b) trigger it manually, so that I can put a custom Lovelace button somewhere on my dashboard to launch it
