In reply to Ciprian Popescu.

I'm not sure about of some of these things on a per-block basis at this stage. I would rather have this set via the Global Styles system that is upcoming. Let themes set the default on a global scale. Then, let users overwrite it, also on a global scale, if they want. After we get all of that in place, we can then decide if we want to provide these design controls on individual blocks. To me, it feels like we're working backwards.
