I hate to be a bearer of bad news, but this bit here doesnt close, like ever, and ive tried clicking everything, is this a bug or am i missing something? :3

Ah, yes, I have the same issue on Firefox. It...well, kinda fixes itself after pushing many buttons and cursing at the screen

On firefox nothings seems to work fine, but it was so broken that i start te believe me ff is broken somehow. Did you see the heat orbs float around?

 

I made the sidebar hide  byt sadly it doesn't support smooth animation, its just on or off 

Is it still happening?

The fix you mentioned earlier (unpin and refresh) worked wonderfully, thank you mur

This has been resolved.
