Unqueue features would be great for DE

Two ways I thought it could be implemented.

Right click in global queue to unqueue the item, shift right click to unqueue that unit and next four, control click to unqueue the unit and all following items.

a hotkey to unqueue unit from a particular building ( not including the one already being produced).

shift + that hotkey to unqueue next 5 units.

control + that hotkey to unqueue all units.

Just my thoughts.
