I don't know if anyone else has mentioned it, but the thing that would help me the most would be an ability to copy and move from one map to another. Being able to load multiple maps at once would be sweet.
Hmm, interesting scenario. Currently I handle multiple maps by running multiple instanced of cedserver on different ports. That worked perfectly fine. But I never had the intention to copy areas between maps, which of course is not possible that way.
I'll add the feature request to the bug tracker. I can't promise you, when or if I'll implement it. But at least you drew my interest ;-)
