While we’re on the subject of shell extensions, this little program (135Kb) will do loads of cool stuff. For that paltry footprint, you’ll get 4 Virtual desktops, programmable window icons (like your close box etc) and the ability to set the opacity of windows too.

For instance, I really like the idea of having a window in “always on top” mode. This can be done now by programming dm2 by right-clicking on the taskbar and going into the action menu. You can program all of the three standard buttons on a window to do different things if right click or middle click is used and also with shift/control combinations.

The program also has the ability to support it’s own sets of plugins, which as the program is open source means there are already a few available with the app.
