I like to group units into sort of divisional sized groupings. After a while I get an intuative feel for what these groups can achieve before pausing advance or getting too spread out. For me it works better that way for keeping a grasp of what is going on. Naming units helps that.
Plus there are some favorite and famous formations that I like to put in.
