I would very much like a menu of options dedicated to Shaders. I feel this would greatly benefit anyone who makes shaders for GZDoom like Pixel Eater, Rachael, and all those that enjoy their shader work.
The menu would house the options for each different shader and would allow, at will, the activation and deactivation of shaders. This would be most useful for shaders that don't already come with the option to turn them on and off.
He said shader 6 times in his thread, that's 6000 points!
