I was hoping that by now IDEA would have support for floating an editor window so that the viewing of 2+ source files at the same time. Moving from window to window via a tabbed pane is irritating, especially if you are trying to match keys/values in a resource bundle, or comparing strings and such. Or just trying to work on 2 files at the same time.
Anyone know if there are plans for adding this to a future release? A plugin perhaps? Or is it there?
