Edit: Sorry for the delay, I hope the performance issue on the video page is now improved with the release of 2.1.1 Original: Hi, currently working on making it lighter, the methods used to intercept YT code are heavy and need to be improved, though this is mostly limited to logged in users and when the comment section loads. Volume boost was never a feature present in Iridium, but controlling the mini player is a matter of moving it with the right mouse button. Resizing it was not re-implemented though, I need to find an easier way to do it that is not as complex as it was before.
