I added the ability to check your level and EXP by mousing over your main or sub class icon. I also added a respec button as requested.
As far as organization goes, I don't think it's really an issue currently. The skills aren't thrown in a random order, they're shown left to right in the same categories they were separated in. You could argue that it's slightly less visually clear and you might be right, but I do not think it's particularly worth the (extensive) effort that would be required to change it - it would require a bigger interface window, require manually positioning every class's skills (the old format would not work), and essentially reprogramming half of the interface. Again, at this time I don't think it's a wise use of hours for something that isn't really a functionality issue and more of a preference one.
