Not saying i want it like minecraft, but switches that activate doors and traps would be nice. Allowing turrets to be operated outside of dominion would also be a good improvement in my book. Maybe marines could be placed on maps and creations, and be able to operate screens and monitors. I love the edition of locking objects, because I was tired of people going my session and deleting everything. More fx effects like day, night, sunset, dusk, dawn, etc.
