Sadly, yeah. Even if ugly and not so up-to-date, it had the most precious thing games lack nowadays, which is clarity. You never had to scroll with your mouse wheel back then. But times change, and SL3 approaches...

EDIT: I gave it some thought over after looking. Maybe if you hover over the class it will show a pop up with its level and experience like the Character Stats one? Some classes' names are too big for it to be displayed smoothly like Soldier (LV1), like Grand Summoner for example. This could also be a thing in term of the skills, giving them some general information like it's SP level/SP max level, as requested.

It's big brain time, Dev!
