Giving apps accessibility access is the one thing that has led to a slippery slope that has caused me to unlock the homescreen from malware on many an Android. The rub is I really want an app like this in some way so I suggest forking Newpipe and building this into that with a simple way to add the various APIs from whatever streaming service.
I would also like to see this done as a flappy bird-like ;) doom and undoom(?)
