A cosmetic change yeah, but it would be nice if exp bars only filled in up to the current level. Currently they fill in the exp of each bar.

Hi! The current design is meant to show progress towards each level. For example, if you have 90% of the XP needed for level one and 50% of the XP for level 2, it'll show the first two bars at 90% and 50% full respectively.

I can certainly change that if players find it confusing though; could you add a comment on the Lookup Anything mod page to see what other players think? I'll close this ticket since I don't track questions/suggests on GitHub, but feel free to comment there if you'd like to discuss further!
