You prefer whitelist approach, I prefer blacklist approach and for some it won`t matter at all (locked in landscape) - so what? Let them decide. And I don`t care if it was some "debugging_dev_only" option or not, because it is working for me and does what I want - right now I have pierogi locked in landscape (like it should have been and like You intended it to be) with bunch of other apps in portrait.

I`m really trying but I don`t see where is an argue here, because surely not about having a possibility of choice?
