Assigning support tickets to users other than Admin level?

Hey this is a cool plugin thank you.
However there are some very nice plugins out there that I'm looking at that have more features. I like using my WPMUdev plugins and would like to contribute to your plugins being the best out there!

It appears one can only assign a ticket to an admin level user?

I need to be able to have tickets assigned to other role level users.
I also need to be able to specify which users get notified of new tickets.

Can you do this? Can you make this mod please?

Thanks,
Joe
