I've figured it out: Control + Shift and then right-click to open Properties, and then I'm able either to rename or delete.

I've tried that, but it doesn't seem to be working for me. I'm able to highlight the collection, but not go any further than that. I'm wondering if it's b/c I'm using this program via Parallels on a MacBook Air?

is it possible to rename a collection once it's been created? Or delete it?
