For the permissions in Roles, I would like to see an exclusion field for customers. When you get a lot of customers and you want to limit to everyone but this one company it requires you to select the 100's of clients and then leave out the 1. A simple allow all but exclude this one would work much better.

And it would also be nice to select specific servers that the technician can have access to, as it stands its all or nothing. It would be nice to specify within the tech role what servers this tech can access versus all or nothing.
