Just what I wanted, replicates the twitch theatre mode which I'm a big fan of. Why youtube hasn't implemented this themselves is beyond me but this works perfectly!

I was previously using a similar add-on but switched to this one which not only functions fantastically, but also lets me make the chat background transparent and on top of the video, a feature I did not know I needed.

Works perfectly, finally an appropriate way to watch VODs, no idea wtf Google are doing but with this extension I don't need them

The Chat Box is slightly to big and I can't seem to fix it in the settings so now 1 chat line (the most bottom one) is either missing or incomplete. Other then that great add-on!

Amazing addon. Works incredibly well.

This is an amazing addon that anyone who watches streams on Youtube should have installed.

However, there are two (very minor) issues with the addon that I hope can be fixed in a future update.
1. There seems to be a hotkey (T) used to toggle the mode on and off. This hotkey remains active even when the video isn't focused. So if I try to write a comment in the comment section, pressing T toggles theater mode and makes it impossible to continue the comment.
2. Youtube did a recent facelift update and changed the data that is displayed near the video's title area. Now, if you turn theater mode on, this new data is stuck and overlayed over the video and doesn't go away.

Exactly what i was looking for!

This is amazing. Finally youtube using the whole fucking screen without wasting space!!
God bless you. 15/5 stars.

Amazing extension, it wonderful to take advantage of all the space, would be the perfect extension if it can be possible to do the same thing when watch a video from a playlist, putting the playlist on the rigth side, like the chat
