Quite often I see myself having to go back to the reference I just viewed two references ago or 5 minutes earlier. I then have to search for that reference again in order to find it - which is of course okay. However, would it be possible to include a "history" menu somewhere in the program where you can access recently clicked/selected references? Thanks for a great program - I now have a hard time coming up with new feature ideas... although this one would be really sweet .
