DarkRadiant seems to be the only *Radiant in development anymore, so forgive me if I sound obnoxious coming out of nowhere with my list of demands. A really nifty feature would be to allow texture fitting to multiple brushes/surfaces, OR implement some kind of camera map feature where a texture can be mapped onto a surface using the orientation of a camera or viewport. The reason for this is easy to explain without images. Imagine a cube brush and a crate texture, with the texture easy to fit onto 1 square brush surface, but you don't want a perfectly 90' edged 12-triangle box because you're not making Quake II maps anymore. It's easy to create (up to) 6 extra brushes and bevel these around the six sides of the cube, giving each side an extra 8 triangles for smooth edges. However, now you can't simply fit the 1 crate texture to the "side" of the brush anymore, because it's made up of 5 surfaces instead of 1. Trying to fit the texture means 1 proper fit on the big side quad, but 4 squashed textures around the trim, because it's trying to fit all surfaces individually. Having a way to either "fit to multiple surfaces", or project the UVs from a fixed view, in my opinion would be a tremendous feature to add.
