Command Line functions for Editor commands
It would b really nice for every command available in the various editors to have a corresponding function call (or calls) available from the command line. Even a primitive CLI would suffice. If modders had such a tool, it would be relatively easy to randomly generate a lot of content in a parameterized fashion. Random maps--using parameters not normally available--would be possible, but wouldn't "break" anything because the command-line functions would really just duplicate the "place forest here" command available in the GUI-based editor. An algorith similar to that used by "Dwarf Fortress" could be used to generate maps, for exmaple.
It could be interesting, too, to apply parameter-based randomization applied to things like unit creation.
