i have a few suggestions:
1. Prebuilt themes with colors and a few different prebuilt layouts.
2. Separate buffs from minimap, make it a module of it's own. Add layout for buffs, vertical/horizontal
3. Minimap buttons, gather these up and add them to their own "drawer"/dropdownlist to clean up the UI. Since when you enlarge minimap these button become very large and not so proportional to the ui design. There is an addon for this and i tried it with pfui, the combination became buggy.
4. found a bug with the combination of Luna frames. When i try modifying raid frames size, position. Luna raid frame always reset position to bottom. If i turn off Pfui then commit my changes in luna it works fine.
Questions: When in edit layout mode. How to redock actionbar frames (so they move together)? How to disable stuff? for example the name plate of minimap?
