we are currently planing the next UltraMixer major release so all feature requests are welcome
Actually, your second feature is called “waitlist” and it is already on our todo list. Your first inquiry is not clear to me. Could you please describe this in detail?

(This is not DJ use, but more or less for PA purposes). We use BPM now, but we are not satisfied anymore. And BPM can do this.
