Just sharing this nifty extension called Picture-In-Picture For Youtube, available for Google Chrome. There are similar addons for other browsers. It allows you to watch while doing your dailies
or LFR
so you can still have lots of fun while going through your weekly routine.
That specific one is a Google Chrome extension so I'm guessing no. Of course, since you have a tablet, you can just prop that up and watch videos on it while you're on your PC
