Before adding any more micro-management to the game, please remember how you are going to manage your empire - time is a very precious resource in real life!!
I've been repeating this over and over again but MM has so far ignored me. The game really needs the ability to save in simultaneous games!
The other nice thing to have is the ability to "split" your empire (in terms of the game's mechanics!) so you can get a partner to run part of it, say all the transports and construction queues, while you have your fun flying your dreadnoughts all over the galaxy.
