Some of you might remember a small utility I made called "VPMage" awhile back. Well, I got bored and decided to fix it up.
It can now open and 'edit' files within VPs. It does this by saving files in a temp directory (Deleted after the program is closed); right now, since you can have multiple VP sources, adding a save feature would be confusing. I'm considering changing this to an 'import' feature, so there's one main VP.
So, you have to build a new VP in order for changes to take effect.
You can quickly open files by double-clicking on them, or right-click to edit them in the preview thingy.
There's many more changes, but I'm too tired of coding tonight to try and go through/remember them all.

Todo: adding the ability to add multiple files at once, and creating directories.
Edit: Oh yeah, the file
