Ack, thanks for suggestion. I uploaded 1.0.1 which should also remove pp. It should be available once it's approved. ps. It's available now.

Reply edit: Cleaning up URLs through some external link shared by other people is the only purpose of this addon. This allows me to keep the addon code simple. I don't intend to change that. I suggest looking for a different addon if you really need that functionality or using an alternative YT client outside browser. FreeTube on PC and NewPipe/Tubular on Android are pretty neat FWIW.
