> I wanted it to have a console (like Quake)

Hah!

I couldn't figure out the 3D math for quake, or write a fast texture mapper, so I stuck to working on things like Doom level editors.

But, I loved the quake console so I made a similar thing for my editor, basically just a hot key that swung it down and I could change a few hard-coded variables and added some commands like loading/saving files.
