I often have several workers doing their job at once, but when I click control-Z to find them all, I don't know which one, in the tray, that I have selected on screen. All units have the same icon and the same box/health status. I'd like to be able to see which one(s) I've got selected.
When I select units in the tray, and click on one, they seem to swap spaces in the tray, and so 1 and 2 swap, and I don't know which is the selected/unselected one, visually. I often have to hunt for the one that I want, and that makes me manage the UI rather than play the game.
Is it possible to make it so that a unit, selected in the game screen, can be reflected in the tray with perhaps a thicker border, or different colour, or have a dot in the border, or something that shows "This is what you've got selected on screen?"
