That’s great. I am looking forward eagerly

Firstly thanks for your suggestions.
Secondly the theme builder is more like the one you have suggested viz. a theme framework except it has an interactive UI to help the users create a new theme.

Yes, the builder will have a repo of various php and css files.

BuildPress will allow you to edit “created themes”. *will make it to the release hopefully* It will allow you to export your theme as a normal WP theme, which can be used in other WP installations.

That’s kinda cool idea. I would first request you to have a look at http://wordpress.bytesforall.com/

May be you are aiming for something better. I have few suggestions if you wanna hear

– I request you to make a theme framework than a theme. Because a theme/theme builder with so many options will become very big.

– I suggest you make blank theme or a minimal default theme available with your theme builder/ theme framework

– Let it come along with a big css and/or php functions repository

– Now, once your theme is activated in wordpress, allow users to create a child theme or a new theme

– This new theme will have its own style.css (generated using the theme builders css repo if at all necessary)

– similarly a new index.php also

– The main idea is the new/child theme should be portable i.e. we should be able to use that independantly with any other wordpress installation.

hope it helps
