Thank you for the 10€ donation first of all, I am the sole creator of this Addon and am very happy that you like it so much.
I don't have any other streaming services which one would you recommend to add? Write your recommendation as an issue on github (https://github.com/Dreamlinerm/Netflix-Prime-Auto-Skip).
I think i changed the skipping of commercials to stop 1 second before the actual ad is over so that the series is continued by amazon automatically, so if it is forwarding into the series i have to look into this bug.
