I hope the â€œautomatic modeâ€ of wheel and gear can be set like a switch rather keep spinning With current setting which is it will keep spinning to the clockwise direction once start, we can't really take any advantage of this new feature. I hope you guys can change it to toggle mode just like piston, For example when I hit up, it will keep spinning in clockwise direction until I hit up again or until I hit down (default keys). That will be far more useful that this automatic mood. The reasons are: First: if I want a block to spin at one direction once I start, I can use spin block and the saw. the function is repeated. Second: set it to toggle, like a switch can let us keep a machine running with out keep pressing a key as well as we can turn it off with one push of a bottom. Third: set it to switch can also let us build something that have different speed with out endure the pain of hold a lot of bottom at the same time. Thank you very much for read my suggestion. Hope you have a good evening.
