How can I make formations, and then move the toons as a group in the formation?
I know it cannot be via follow, or that would destroy the formation.
What if you build in a step to set a specif view on your toons and then use a "normal" movement key like you suggested yourself. Then you should be able to control your toons in one direction....

I can't see theres anyway you would be able to use a sort of an "follow" command so they would keep any formation.

Nice info concerning the "Toggle of strobefollow".

My current setup is ctrl+Arrow down toggels strobe on and of. Then I have a keymap to be brodcast to all my toons for each arrow key. Thats how I move the whole group a bit back or forth.
