This is just a small suggestion that would help me out A LOT! I don't know how hard it would be to do it, but make block brakes like regular brakes so we can set them to any speed we want so that the train doesnt slow down to like 4mph.
Another request is like how we have chain lift on all track pieces, well brakes on all track pieces would also be a cool feature to add, like trim brakes on hypers, or downwards brakes ETC.
