What do you exactly mean ?
This?
Also project, folders and virtual folders. I see only the framework icon changed...
What about the icon on the bar below? ("code::blocks" "code::blocks debug" "compiler" etc..)
I renew my idea: why don't add a simple support for themes? Just organize all images inside a zip, with a fixed name, and write a piece of code to allow user to select witch file zip want to use as theme...
