Feedback on the new graphs in Anki/AnkiMobile

@dae

I’d appreciate it if Windows and Mac standard build users could confirm it’s working correctly for them.

Working on Windows 10 64 bit (although it already worked with beta 1 and 2)!

Edit: Just a tiny style change suggestion for the review graph:
Maybe add a small margin between the colored box and the word, and then vertically center it.
