As you might know, the remote control interface is fully configurable
So if no one has time to implement your ideas, you can actually update the interface yourself to fulfil your needs. If I remember correct, the remote control html syntax was discussed in some of the documents in the docs folder. The html files specifying the interface can be found in the webroot folder.
Of course, it takes some time to understand how the remote control works, and the R4 script commands are not exactly the easiest to understand...
A universe is something that happens once in a while.
