New cool tool window features in IntelliJ IDEA 8

During last Devoxx, Jetbrains folks showed us a little trick, which I would like to share with everybody.
It turns out that every docking pane for IDEA tool windows (left, bottom and right) has actually two zones where tool window buttons can be dragged. If you have button occupying both zones in single tool window docking pane, you can have TWO tool windows displayed at the same time in given docking zone!
It makes IntelliJ IDEA UI layout much more flexible (almost like Eclipse) and useful for high resolution screens (does anybody nowadays use anything below FullHD? ;)).
Take a look at the screenshot.
