zFront
This can be a pretty useful utility, though it does have a few bugs. It's a little bit like a file manager for ZZT. You can pick your filepath and choose what editor you want to use (ZZT, KevEdit, ZZTAE).
While it's made a little obsolete by KevEdit being the default editor for all .zzt files, it's a handy thing to throw on your desktop, especially when you want to use the original ZZT editor. No longer do you need to have ZZT in every folder containing .zzt files! No more do you have to spend ages hunting for the right files; you can browse your entire computer for the file you want. One thing I'd liked to have seen is a "favourites" menu or something; Something that would let me zip to my various ZZT folders rather than have to flip through the menu. 3.5!
