First off, this mod is awesome. I'm very happy to see a new version of Gterminal.

I'm wondering if custom operating systems are possible. I'd really like combine the functionalities of "Personal" and "vex_os" (namely the file system, networking, and I/O) and give it a half-life theme, but I'm not sure if the files that make up the two systems are available for me to work off of or if it's even possible to make custom operating systems.

Edit: Actually, I think I figured out how to do it with gmad.exe. If I actually end up making this, is it OK for me to upload as a separate addon? (With full credit given, of course.)
