I found out today that the controls have disappeared. Apparently this is due to the current situation of YouTube vs blocking adv... EDIT: Don't know what's happens, but controls (dis)appear randomly...

Please,
wouldn't it be possible to make a "light" version of Enhancer for YouTube, where there is no ad blocking, but the functions like mirroring, sound boost, snapshot, mini player and others remain? In the current situation, we are losing a very useful tool that has no competition. Users who would like to block ads would ensure possible blocking with other blockers, of which there are quite a few.
