Love vbhacker and wanted to contribute. I was playing around with vbHackMaker today and tried adding 2 things to it.
when editing a hack you have to type in the name of the file. I grabbed some code from vbhacker and now it lists all available hacks instead. that way you can just pick it from the list.
after you make a hack you have to manually save the text to a .hack.php file. now you can just submit the last form and it creates the file for you in your admin dir. there is no error checking involved when writing the file. someone might want to put in some checks. (grabbed code for vbhacker to do this as well.)
of course, I've included a vbhacker file
