Okay, first off, I'm really impressed that Lemmy (the web interface anyway) embeds TIL.vids video player and it just works. Since it's peertube, I guess I shouldn't be surprised. (I wonder how hard it is to create a peertube instance, hmmm.)
Next: as a former KDE dev, I love these sorts of updates. Put it on the background while I was working this morning :)
Most interesting: hiding things from screencasting... if Plasma were ever deployed in an educational context, this will hurt the anti-cheating software that screencasts your screen during test taking. Well, they probably make you use windows in that situation anyway ;)
Weirdest: mouse pointer stays in centre mode... bizarre. Would be fun to couple with an eye tracking camera to create a fucked up feedback loop haha.
