I may need to change toolbar background, heading font and position.
Is it possible to do that with the standard CPToolbar? I was looking through the ThemeDescriptors.j, and there is nothing about a Toolbar.
It seams not so difficult to create my own. Should I go that way?
The toolbar isn't themeable as is (although, feel free to implement that for us. :) )
That said, you could do something like this depending on what exactly you want to do… https://github.com/cappuccino/issues/blob/master/Client/AppController.j#L273
