as long as the app is available in the gesture settings it'll launch it. i know smart launcher does and i currently have it set for that. i'll probably change it since i use feedly far more than i'll use the my magazine app.
edit: oh snap! i didn't pay attention that i posted in the note 3 forum. i thought i was in the gn10.1 2014 forum, lol. either way it's all the same.
