Queued commands have been on the whiteboard for a long time. To implement it would require even more UI in the command screen, so I've resisted. Also, there would have to be some type of naming system in place, as you'd have to be able to indicate what queue to put the command in. I've thought about making it an option of the, 'execute another command' screen, as that would allow commands to be executed with our without a queue. May be a good exercise for the next version.
