I am often not sure how often i subscribe to a channel and also forget to subscribe again. i would prefer to support a channel based on the time i watched the content of it. so for example i would like to donate a previous set amount of money after watching X hours of content of the creator. this could happen automatically or with a notification in the player window ("you already watched 10 hours of "X", do you want to donate your defined gift?"). with this it would be easier for me to distribute my support to different creators and I dont have to manage my donations every time.
