When I click on an explored wormhole the route is shown. After exploring about a third of them I totally forget which ones I've explored and where they go. Any chance of a hotkey that would show all explored wormhole routes? I was also surprised by the one-way nature of many-- for some reason I just assumed go into one and come out through another somewhere...

The only alternative is to write it down I guess, but as the pending master of the galaxy such is beneath my dignity.
Loving the game BTW-- the more I play it the better I like it.
