Select Class
Here’s the revamped step 3 screen, selecting a class. This one shows the traits and description both expanded.
I’m unsure of the best way to present the description, preqs, and class features in a manner consistent with the HIG. One idea I’m toying with is to just show the traits from the current class level and have an “Information” button that brings up a simple, read-only popup window (either a rich text or HTML widget) with a close button.
You’ll note the warning icon next to the giant racial level; this is how any class with unmet prequisites would be displayed. There will be a configuration option to simply not list unavailable classes, but many (most?) people like to plan ahead for prestige classes and will want to examine the features and preqs.
