Looks good to me. A couple of minor gripes
1. When writing a VP file it doesn't append the .vp extension if you don't supply it yourself.
2. Although you can select multiple files you can't move them. It simply picked the last one I selected and moved that.
1) Yup.
2) Yeah, that one was on my todo list, but I decided it wasn't vital enough to postpone release. Multi-selection isn't really supported by anything else, either.
Still, I'm surprised those are the only bugs that popped up. (Pleasantly surprised, that is.)
Apart from that it looks pretty good
I found it much easier to use than VPmage (the UI on that one confused the hell out of me for a long time) but this one was much cleaner. I find the ability to edit files very useful.
Only major drawback I see is that this is going to give me all kind of support headaches from idiots altering the root VPs when they really shouldn't have since you've made it so easy to do that now. 
Yeah.

I had meant to add a CRC32 check lockout, but I didn't get that implemented - it's part of what I consider the CVP package, as I don't want to have more than one CRC check (eg the nonstandard fs2_open one) running around in the codebase.
Do you have a permanent location in mind for downloads? I'd like to get this one into the FAQ when I update next.
Not really. If I had some kind of webspace that I could upload it to and track the number of downloads I would use that. Unfortunately I don't; and everything decent I know of, you have to pay for. ('decent' = free, fast, no ads, no registration or similar BS)
