Excellent idea to fork this plugin since it's exactly what I needed. Hope you haven't given up on us!

It would be great to be able for the user to get a list (table?) of all their tickets and their status since they often want to check back and see what's happening with their ticket. For example if you create a page and add [LIST-USERS-TICKETS] or something.
Sure, they can check their ticket using the URL:
www.domain.com/page/?ticket=<ticketnmber> but the user doesn't really know that.
Seems like the permissions are already built-in. If a user tries to open someone else's ticket they get "You are not allowed to see this ticket."
I got some other ideas too for features, but let's start with this. I think it's a good idea to keep this plugin pretty simple.
