Improve management of multiple editor windows

With 1.4 each edit window has it's own entry in the windows taskbar. This can be confusing when searching for a specific window.
One way to improve would be to introduce a special window-list that can be summoned on a hotkey.
Or else the main CN window can be extended to accommodate overview of currently open editor windows.
