To give that idea serious credence would mean being able to parse the inputs and outputs, and make the togglable settings on each.

When it's a simple number, that's not hard. When it's a file, it's a lot harder, since there's a lot of non-file files (fifo's, directories, symlinks, hard symlinks, network locations, mountpoints, etc). And don't forget that you can pipe stuff in anything that looks like a file.

It sounds simple, but for things like ffmpeg or openssl, the possibilities are just stupid complex.
