Hi andrew, i actually love the idea, and could try when i get some more free time, but being very new to all of this is might take a while.... just wondering if all the peoples here could start thinking about the screens/functions required.

Basic functions:
List all themes available
Set Theme
Delete Theme
Create Theme(Needs splitting down)
Edit theme (Needs splitting down)

Creating a theme:
What parts are needed for this? - known list of all requirements needed, and what any control files folders are?

Editing a theme:
Determining what parts make each theme
Showing previews
ability to edit certain parts (Apply function?)


And above all - i'd suggest very good bug / issue checking (Don't want a screwie theme!)

edit - Andrew - did you put this as an idea for GSOC?
