The first feature is not in open stage control and there's no plan to implement it. Some have tried to do implement some physics using a custom module but that's quite not as convenient.
The second features makes me think of the ephemeral property, but I'm not sure if that's what you're after.
As for the third, I'm not sure to understand what it means, but it doesn't sound like somethink you can do with open stage control's multixy.
In general, there is no plan to implement any physic, sequencer, or timing critical features in o-s-c.
