Shortcut To Swich Desktop Folder Location

I was thinking of a way to make life easier on a computer, and I came up with a sort of multi-desktop system I would love to have on my computer. I know a bit about registry editing, but not enough to do this since it would probably require creating a small program. With a simple keyboard shortcut (I'm thinking of something like Shift+Windows), the computer would switch the registry value for the Desktop's folder location.The idea would be to have a small program where I can set up a list of locations and give them an order in which they would cycle through.As far as I can understand, just changing the registry value would not change anything until I logoff/restart, which implies that there has to be some sort of task running which refreshes the position? Now is the part where things might just be too complicated to be possible : ideally, it would be nice to have options to change the background image depending on the folder you are in and, if possible, have the name of the folder written somewhere on the screen (to avoid confusion and messyness).Now the coolest way to do this, according to me, would be to cycle through saved themes when you cycle through folders, which would allow to change window colors etc.I know this is something big and probably not easy to create, but the more I think about it, the more I love the idea... It would make life SO much easier and force people ho have ultra-messy desktops to be a bit more organized.
