Hi there. I am very happy Graphene OS exists 😍.
This might be a low priority bug:
Main profile: Gboard enabled, sayboard enabled, aosp default keyboard disabled.
Profile 2: aosp enabled, no other keyboards.
When I use the profile 2, and then go back to main(terminating session or not, doesn't matter) I see that in my main profile the AOSP keyboard gets automatically enabled.
I change languages frequently so having 3 languages per each keyboard (3 Gboard and 3 AOSP) gives me a list of 7 keyboards to choose from when changing languages, with this bug. I then go to settings everytime to disable AOSP keyboard and get a shorter list of languages (4 = 3 Gboard + 1 sayboard).
