Improvements on features that are in Insider channels

I agree that Edge Canary is very stable for a beta version (or the alpha version of the beta versions).

I use the PIP on my Chromium browser. I have to admit it's convenient to have it as a clickable option on the upper right hand tabs of the browser. On the other hand I hate clutter and too many icons filling up the task or top bar. I guess it a matter of personal preference. Maybe have the option to toggle between having it showing in the extension tab bar or only access it via right clicking the screen page and running the PIP, especially when watching a video page. 

But Edge Canary in itself is very stable with only a bug every so often that's usually corrected in a day at most. So I encourage others to beta test it out.
