Okay Michael, I see what you're saying. I don't think that having suggested commands or an autocompletion feature would really change the overall workflow at all, though. Considering that MoI does allow you to type in commands anyway, this would just make that feature a little more user friendly. Everything else would still stay the same; I don't expect MoI to force you to select all the subsequent options for each command from the command line like Rhino does (though personally I like that method). Besides, aren't there some commands that don't actually have a button in the GUI associated with them, and you have to know what they are beforehand? (Correct me if I'm wrong.) An autocompletion feature would help the user discover those hidden commands.

Anyway, I know that other things have much higher priority, but I just thought I'd suggest it since the command-line feature does exist but really isn't discoverable at all. (After all, there's nothing that says you can type commands in the box, you just have to know it beforehand.) Just some food for thought.
