Just wanted to give some feedback and say that I love the new look and feel. I've felt, over the last couple of versions, that IDEA was becoming a bit less efficient with it's usage of screen real-estate. For me, the new LaF is real step in the right direction.
Could use some better feedback on some UI elements for what's resizable though - like the background tasks window. Of course, I've no idea how to do that and be effecient with screen real-estate at the some time though. At least a change of mouse cursor or something would be nice though - like the divider between the editor and project panes.
