I've been looking for an extension that does just this: let you add streams from both twitch or youtube (or others) and im glad i found this one.

My only piece of feedback i'd like to give for this to be perfect would be:
1) ditch the red color as it look way too contrasty with the black background
2) clean up the ui a bit, it feels a bit too cluttered
3) change the stream title for the actual stream channel name or at least add an option in settings to enable so if desired.
4) add a search bar to be able to find specific streams quickly either online or offline.

Apart from that, i do love how intuitive the extension feels to navigate, works very well too. Adding a twitch account or youtube streams was a breeze of a process. Nice!
