• I like the borderless look, fits better in the UI. Even better if you manage to give the add-on list a different background (like Achievements window, for example). If not, a vertical divider between add-on list and settings pane should suffice.
• I don't like that a stand-alone LAM would be required. Somehow I got fond of how most add-ons bundle everything they need.
• Categories... hell yeah! But there's a trap. ESOUI categories are too many, overlapping, and blurry. For me at least. There should only be a few.
• While you're at it, please change CreateTopLevelControl to CreateControl in each and every control constructor: http://www.esoui.com/forums/showpost...99&postcount=2
