LoKey v1.0.2
It's "usable"!
The code has been updated to target API level 27, and some small but major bugfixes have been applied so I can pretend this isn't abandonware:
- Default settings are applied automatically, even if you don't open up the preferences
- The "done"/checkmark key actually works as you'd expect - you can use Chrome or unlock your phone if you hate yourself enough
- If the signature feature is enabled, Shift+Done prevents it from triggering.
