I wasn't talking specifically about interactivity, just being able to run 
a command by manually typing it in. And I've just seen that you CAN do 
this! In the gis.m output window, you can type in any GRASS command you 
want and click run and you see any output in the Window above. That's 
exactly what I was looking for - I think it's really cool that GRASS has 
this. :)
