If you want to move around within ESD you need to make your own copy, but the problem is that the ESD in the Foundry is out of date. (DS9 is out of date too, but it's not as bad since it's functionally identical just has different lighting and a few missing signs.)
Has there been any word on when the updated ESD and SOL System Maps will be added to the Foundry? The new ESD has been out for over a year now and until this is done, a Foundry Mission of mine has to stay on the drawing board. It seems like such a simple, fundamental concept - just like allowing an NPC to beam off of a map. Beaming out is a simple, fundamental concept of Star Trek.
