I have just adapted YACO code to Oreo (and with a lot of internal reorganization of a very inorganically grown code), I read about Android P, that there will probably be more restrictions for apps with “background” execution.
That means for me that maybe Kitty can’t be further developed because Google makes it too hard for me to maintain a free app for their every growing restrictions.
With YACO the ambition was first and I use it myself every day (ok, Kitty too.. sigh)!
Wait and see, but I find Google’s path questionable.
