"projection mode = orthographic, and then doing the for the camera viewport?"
No, they just position them at a fixed distance from the camera, and then scale them to the right size so each texel falls under one pixel.
"I checked out your GUI system sswift, it looks really nice for a game GUI system... unfortunately, I'm looking for more of an "3D app" GUI system, with tree-lists, scrollable stuff, etc."
Well my GUI system is designed for making your basic game menus and stuff. I don't want my games to look like windows apps. :-) Scrollable stuff I've considered adding a few times, but it would make the system harder to use. But it could be done using more cameras.
If you want a windows style GUI there's several to choose from. Just look in the tools section of the website. Eole is one I've considered using.
