This is a HW2 leftover annoyance which makes strikecraft micro a pain.
Let’s say you use a strikegroup to control your interceptor cloud, and keep them selected so you can see which wings need docking. Now whenever a wing dies (or sometimes just randomly) the order of the unit icons appearing on the lower left are shuffled.
Starcraft 2 addressed this issue by leaving blank spaces where dead units’ icons should be, and the order only gets re-shuffled after re-selection.
Could we get something similar?
