[F]Quick-load at Main menu: When using an unstable release F2 comes in very useful, it would be nice to be able to use it from the main menu
(B)Instant building at the start: If you select to use a bare base, you can build various building instantly, however you only get one shot, if you leave the building page and then go back you can no longer build stuff instantly. I think it would be better if aslong as the time hasn't changed you can build instantly (perhaps just in your primary base, would be a needed limiation)
(B)Instant Destroying of building, if you build a building then instantly decide you don't want it (as in no time has passed or as in youve not even left the editing screen) i think you should be able to destroy it without it costing you anything (e.g you get your money back).
