I find myself using Find Declaration quite often, but then I become lost. Where did I just come from? This happens too easily for me. My train of though derails.
So it would be sweet if Find Declaration had an opposite command: Return to Origin.
One could then browse around and read the declaration - even make a change here and there - and Return to Origin would get you back.
(Or, perhaps it could be named after that famous song: '"Return to Sender". "Address unknown..." etc.)
