Issue: Select All Option for VMs

Okay, so I was trying to clean out my VMs yesterday, and part of the reason that I never finish doing it is because it's daunting to have to click each little white box one at a time for 20 pages and then clear them, since only 200 can be removed at a time. I'm fine with only being able to delete 200 at at time, but is there any chance that an option can be added to 'select all' VMs on a page to make it go just a little faster?

And, this sort of ties in, but is there a way to 'hard delete' them? Right now, all that shows up is 'this message has been deleted by celtic7irish'. I don't know if that shows up for everybody else, or just for me, but I was wondering if there's a way to permanently delete the VMs?
