And what about this great, stable, fast and extremely simply to be used ( you can also use it without installing it ) windows shell replament
, gpl licensed?
It's extremely similar to linux blackbox, and has fully customizable menus, keyboard shortcuts, themes ( if linux themes are really compatible, there are eons of them ), virtual desktops support ( extremely useful imo ) and plugins.
And a really good editor, written in java, gpl too: jedit
: it's really feature filled and there are eons of plugins.
