I'm just afraid that if everybody gets to wish then the theme will get a gazillion features or something like that. But of course we could make it modular or use dynamic loading of modules. There are cons though. Modularity more or less means that you have to group things and dynamicnes (that is a word now I've heard) might be somewhat buggy for some maybe. I've never heard of a theme that uses it to any great extend, other than one that I'm working on now but it's not released, so that would require some testing.

Or we could of course just pick the ten most wanted features or something like that, but that would be to plain and simple.
