(Note that I have no idea whether this is a discourse problem, DevForums, or just YouTube. But I’ll put this here for now.)
So technically. I have this group known as DevVids where you can embed YouTube videos for on break development entertainment. However. On the DevForums web app. You cannot use full screen. Screenshot of this:
The feature request part is the ability to put the video into full screen.
If this is to be added. It would improve my use of the DevForums as it would fix a lot of DevVids problems.
