I see that you added navigation bar options for each app.
For me, i can change the nav bar color, but not the icon's tint (it resets itself when i get back the the activity window).
also, after changing the nav bar color and failing with the icons, i could no longer reset/change the nav bar to some other color.
EDIT: oh, and when i went to GEL stub to see what happened, it offered to go to the real app, but it ended up in some sony app instead of google search :P
