I just started playing the Alpha of PA and I feel that it would help quite a bit if you could see numbers attached to the building in your que to quickly see what sequence they will be built. That way you are able to evaluate whether to continue with pipeline or change it depending on tactical events in the game. Furthermore it would be good to add an drawn route for units so you see where they are headed and what their pattern will be like. This is valuable if you are close to enemy artillery or scouts, want to sequence an attack or simply can't remember what you asked your units to do
I think this topic should be checked as "feature incomplete". Seriously I totally sure this functionality on the way and will be available anyway.
