First of all, if score could possibly be shown there without removing the possibility to see pp's (now that I have the level under, I want to see my pp's "instead of level" to the right of score ^^") because how you put it isn't exactly how it was in my head(happens), I was thinking more about a third line(I give you more infos later in this message)
I don't know exactly how the bar acts around 50% of it, but it feels weird at that area, maybe you could think of something toward that? (I don't have suggestion for this one, I give my opinion alone :c)
maybe change a bit size of letters to make somehow a third line of stuff to show when an option like "[ ] Use third line"(without the option it would be like now, and with it, it would be tinier but with a third line of infos...So we also can choose in what order we want the infos=>for example score and accuracy on first line, playcount and pp on second and the exp bar at the end, or accuracy on first line, playcount with pp on second, then score on third with the exp bar)
(Very good job so far, I love it. And I hope you like me with my many suggestions since I know your signature <3)
EDIT(5 seconds after posted): Maybe we could also have hex color choice for exp bar colour?
EDIT(another 10 seconds): neither the 2 online indicators seem to work for me, maybe I did somethign wrong?
