Again, something I found on Virtual Plastic. A little app called miniMIZE. When you minimize a window it makes a thumbnail of it on your desktop and removes the item from the taskbar. To restore it you click on the thumbnail. This can seem unpractical if it's hidden under other windows, but you can assign hotkeys to bring the thumbnails on top.
Unfortunatly I haven't been able to try it for more than a couple of minutes because it got some issues with WindowBlinds and ObjectDock. It did work initially, but then I changed the thumbnail size in the settings and it stopped working. I've reported this to the developer and I am hoping for a fix. Not sure what to make of it yet as I am unable to test it further, but you lot can always give it a go. Just note, if you got WB and OD, don't do any changes to the thumbnail settings as it might very well stop the app from working.
