Enhancement request: Toolbar background color per tab category

[ScriptHippie]

Setting "Bling My Tabs!" allows to set the background color of the folder toolbar, which is nice to have.

It would be a great enhancement if the toolbar color could be customized for each tab category, thus allowing a color-coded environment for each category's pupose.

This one is difficult as I do not store categories separately, they are just like tags and are stored in the tab structure. Which means if you remove a category from all tabs, it disappears. So it would require rewriting the whole storage structure and possibly have additional management tasks for users (who now have to also view / manage categories as a separate entity). Not sure the squeeze is worth the juice; I will think about it.
