Feature to split both "Video/Game/Desktop/Screen" and "Facecam/Camera" into separate feeds, and then displaying them both in the same video player. This would then allow watchers to move it around or disable it completely on top of the video. If for example, they are only interested in the Gameplay etc

A side effect would also be, any streamer who likes to compile stream clips etc can review the stream without his facecam something which is great to have in streams but can be annoying.

lastly, this doesn't necessarily have to apply to just webcams. Overlays and Notifications could also work in a similar way. Each "video" feed being separate and only displayed if the watcher wants it to. Same applies to finding clips, you get a really awesome clip from a game, but just as it happens a donation or follow pops up basically interrupting it. Having the ability to disable that after the stream and have just the raw gameplay would make a huge change to content after streaming especially those that don't just stream!

PS. Thanks for the awesome site!
