So this part of character screen is practically over. As you can see in the gif, it has custom tooltips, build lists from available information and shows plenty of data on quick glance. New text wasn't proofread yet (and probably could use more fluff, but sadly i'm out of writers).

There's still need in some sort of custom gui (borders, panels, buttons etc), so I'll consider any offers if anyone willing to help with it. Next comes interactions and overall rules/jobs tabs.
