Well, I don't know about any plans for the timer, but there are texture files for new Transwarp locations in the Tribble Season 2.0 pre-patch. There's icons for Transwarp to DS9 and K7, so at least we'll (hopefully) be getting those two soon.
edit: Just noticed an icon for Starbase 39, as well.
Right now the transwarp ability goes back to one station, Starbase 01 or Earth Space Dock on the Fed side. Can we get it to pull up a list of locations to go to?

Maybe this will also help spread out the server traffic at social hubs.
Hmm..don't get me wrong but i find the transwarp ability nearly useless. Space isn't that big to make it a usefull ability. If space would be nearly 100 times bigger or atleast 10 times bigger it would be usefull. Even if it would take us to all known space stations at present it wouldn't save me much time.
