Does not work with Hacker's Keyboard (https://github.com/klausw/hackerskeyboard). It closes itself after a few deciseconds, whereas usually the permanent notification feature can be tapped to open and use a keyboard anywhere. Or maybe I haven't tried using it on the new Android 11 yet and yet another of my favorite hacks broke.... now that I try it elsewhere, it seems this app got broken by google breaking userspace again... Never mind, looks like I'll have to go and fetch a USB keyboard for this in the future :/
