Please add support for refresh groups as well.
Where I currently work, we have development DBAs and physical DBAs. In general, I never need TOAD for anything since most of the system DBA work is done by the other guys. But development DBAs tend to have much to do with creating, maintaining and troubleshooting MVs and MV refresh groups.
I too would love to see this support added to PSD so I can cease needing TOAD for anything.
