Time is money, or are you going to waste it?

+1000, in the late game on the HL template, this is critical; otherwise, you simply have to choose what is more important and ignore the rest.

However, this is also an element of strategy: being able to skillfully determine priorities. At the same time, I have repeatedly watched streams of games by hardcore players who only use the army exchange and artifact transfer hotkeys: separating units into free slots, detaching a single unit, dividing a stack, merging stacks, etc. - all is done with the mouse and by scrolling with the cursor. This doesn't apply to Kobra; he has everything perfectly organized, but otherwise, it's a complete mess.
