Request:
Let ctrl left click on a unit or building mimic a double click action (all units and buildings that are both on screen and of the type clicked are added to selection). OR Have a toggle option that when toggled on, causes ctrl left click to mimic a double click.
Reason:
A ctrl left click is easier to execute than a double click. When the screen resolution is high, the camera is zoomed out, the game speed is set to Fast and units are moving quickly across the map, it is both slower and less reliable to double click a small moving unit quickly and with high accuracy. It is better to click it once with ctrl held down. This would be a big quality of life improvement for many players. It is a feature present on other RTS games including Starcraft and Starcraft 2.
