1. You can click an object of a certain type, then right click it and choose Select->Same Type from the menu. This selects across all databases on the diagram. Then right click and hit Properties on the menu. If you change the Fill Color and Text Color, those changes will be applied to the entire selection; ie. to all objects of that type.
There is a bug in the 2.0 release whereby getting Properties on a large selection fails. This will be fixed in our forthcoming 2.1 release, which will be a 100% free upgrade from 2.0.
2. Thanks for that one - I'll pass it straight on.
