Just keep in mind we need preview style function working in admin before any of this
[/quote]Seems to me that adding user selectable pre-defined themes that have restricted visibility (by TL or group, for instance) would be an easy way for an admin to preview a new style. 
I wish I could take credit for this brilliant idea, but it is straight out of vBulletin.
The theme picker could be shown to a user who has the ability to pick themes (by TL?) and there’s more than one that he is able to pick given his credentials. So an admin could define and save a new theme but only permit it to the admin group, and then select it in the front end and give the system a test drive with it, all out of sight from regular users.
And slightly off-topic, on the New Color Scheme page, sure would be nice to have some sort of color picker built in.
