http://forum.altap.cz/viewtopic.php?t=197 reminded me of one issue I'm experiencing when trying to compare differently named files in different directories using internal File Comparator plugin. I'm not sure it's a bug, but I'd vote for this to be "fixed". Let me explain.

I expect the same behaviour as is now when I compare a.txt and (other version of) a.txt in left/right panel (focused only), where there are both prefilled.
