Extension is pointless on YouTube.
I have noticed that youtu.be/videoid redirects you to youtube.com/watch?v=videoid&feature=youtu.be Then, youtube.com/watch?v=videoid&feature=youtu.be is changed to youtube.com/watch?v=videoid (by the extension) .
This can be improved by making the extension change youtu.be/videoid to youtube.com/watch?v=videoid directly (instead of relying on youtu.be to redirect)
Kinda pointless to remove the &feature=youtube part since the click has already been tracked and logged at youtu.be
Hope it made sense. Not technically a bug, but the extension is pointless on YouTube.
Love the extension. (Could be better if allowed to set our own rules by simply adding them as we browse) :)
