I think I've read every single page of this thread. This program is amazing and the support you give it PG is insane.
I don't really have any suggestions right now, all you other people already got that covered. Someone mentioned Propper and twister addition which would be very handy if it was implemented.
Anyway, since I only really map for Source this isn't really for me right now, but when you are going to add support for Source I will want to help you as much as I can. (Even though it looks like you wont need it) With vmt and version 7.4 and 7.5 of vtf...
Anyway, keep up the good work! I'll be sure to lurk this thread everyday from now.
