Annotate Context aware OS

Have you ever been annoyed by the never ending quest to organize information on your computer? This idea solves that problem:

Normally when you organize stuff on your computer you start with your files. It’s annoying but it has to be done. Fine, so you organize all your files... but as soon as you are done with that, you realize that files are not the only thing you store on your computer. You also likely have:

Favorites/bookmarks
Emails
Application shortcuts

All of these have to be organized too. (for example, why would you want to see your game shortcuts in the same context as your application shortcuts). That means you now have to organize and synchronize the categories for at least 4 different types of information. That task is obviously a waste of time.

The solution is context aware OS. You would see a context selector somewhere on the screen that would let you switch between different contexts. For example, you might have the following contexts: Ideas, work, entertainment, job search, and pets (you could create any that you want). Now, when you enter one of these contexts, all you see are files, shortcuts, emails and applications that are relevant in that context. When you enter the “work” context, all your entertainment stuff like YouTube bookmarks, games, savegame files, and movies disappear. It’s as if you enter into your office. Do you have a playstation plugged in at your real office? I doubt it. Everything is neat and organized, you have everything you need to get your job done. It's the same reason why the stove is in the kitchen and not in the middle of your living room. The best part of this is that as you work, the OS knows that you are in the “work” context and marks any new bookmarks, files, emails and applications that you install as belonging to that context. When you want to take a break, and take a break watching funny stuff on YouTube, you just switch to the “entertainment” context and there you go, all those bookmarks are there ready for you to browse.

Now for the implementation: How it would work is that every time the OS requested to see a list of files, it would go through a "middle man" who would make the following decision: If the file is in the current context, show it, don’t show it. This would work well for files and folders as well as favorites/bookmarks which are for the most part just files and folders. For emails, things get tricky. The email client would have to be "context" aware and be capable of filtering out all emails that are not in the current context as well as marking emails with metadata indicating under which context they were created.

A research project that accomplished something similar like this has been baked with virtual rooms (you actually had 3D interface and you walked through the different rooms). This is a waste of time, I'm proposing the same concept but with no walking around, no fluff. The same applications you always used just with the ability fo filter out all of the stuff that doens't belong in that particular context.
