Masters need override capability
We are looking for a tool to use across a large organization. Because of this, masters will be very important (and widgets almost useless). We need the ability to push a new master to a project and across projects, but we also should be able to change styling at the instance level, or even to override master dimensions. For example, I may have a master that is 120x80 pixels and colored blue. I might want to make 5 copies, color 3 of them pink and stretch 2 of them in one direction. Changing the master color should update all blue instances, and changing the master size should update all of the non-stretched instances. Going to the instance I should be able to remove the overrides easily. Balsamiq does this, but lacks any animation, so we are still looking for a solution.
