thanks! 1. oh, of course added stop to the list of player/on-page buttons! https://github.com/code4charity/YouTube-Extension/issues/842#issuecomment-809077449 2. buffering in advance is critical. please join us & add your details. Just wrote the long answer for you here: https://github.com/code4charity/YouTube-Extension/issues/581#issuecomment-1014280878 --- Please keep in mind it can be so frustrating, if not wrong to pressure us based on the one feature you grew fond of years ago, which we have not, which might be for a good reason. You might want to give 5 stars to support the cause rather than making it seem impossible for us to get 5 stars and get anywhere near as much visiblity as our work deserves. ----Browser extensions are unfortunately supposed/presented to be small/single-purpose. We still are avidly providing a 100 of the most wished and requested features without 100 times more success than easy extensions. This is many times more teditious than making our own site which would be fun/need no maintenance. We are volunteers. Youtube has a billion times more money than us. Many smiles!
