i love this in every way. here are some images:

Improvment Areas:

. make it an official setting in khan academy

. it seems that the background comes only once and when you reaload it is gone(might be an error on my side)

. the background seems to be the one i was using last, namely Photon 1 (or two). when ka had backgrounds, they were also seen in the avatar select box,which is plain gray now.

.mabye a full dark theme?

Compliments:

. i love the resizeable screen

.  the additional stats are super cool , but what are forked programs

. my fav coding  box theme is pastel on dark    

. the best feature is the themes

that being said hats off to the people who created this and as always, khan academy
