Many thanks for your tireless dedication to this wonderful project.
I have the PP app on Android TV Boxes using a custom playlist and Custom Logos for several old folks.
The PP app is set to Autostart and they use a simple remote with UP/DOWN LEFT/RIGHT and OK. They don’t need to see the Main Menu or Context Menu .. If they accidentally hold buttons for too long, it brings up menus that confuse them, they hit UP/DN/Lt/Rt/OK and they are lost and need help.
The easiest option that I can suggest would be to have a long-press duration setting (if its not an OS system setting) so that it can be set to a very high value?
