@hotlittlewhitedog Great work. I do have a question, how are you distinguishing Android TV verse standard Android? I use XMBCLauncher on my nVidia Sheild TV and my concern is that if these features rely on the leanback launcher that myself or anyone who replaces their launcher will miss out.
Kind of related, I added a note about Multilanguage Keymap Redefiner in What types of apps are you missing from the FOSS ecosystem? - #143 by thrilleratplay. If it were open sourced or rewritten, it would probably alleviate a lot of the headaches of trying to make these F-Droid changes compatible for every possible controller for Android TV.
