This is a simple Data Broker addon that displays each of the character's professions with the current level of each. The icon for each profession is used denote each profession, and it's sized according to the font size used in your Broker display. The tooltip shows each profession name with the current level/max level.
A Broker Display addon is required, or FuBar with Broker2Fubar. I'm currently using ChocolateBar, but any should work.
1.2 - Fixed the icon issues, but if icons can't be found it now displays two-letter abbreviations instead of the full profession name.
