Spatial vs Navigation User Interface (Editorial)

Many operating systems are choosing if they want their file organization as spatial or as navigational in design for users... Spatial design builds around the fact that it's easier for users to locate objects by their location, size, view, colors and so on that don't change without the users explicit actions. Navigational design builds around the fact that instead of browsing every object in it's own window, you browse from a single location using functionality like history, bookmarks and path jumping to easily go through deep levels of objects. The problem is that choosing either one has it's limitations. While spatial might be superior for small simple users who don't have much objects it's a pain for using on web-sites or with users who have a vast amount of information to organize. Their is always a maximum a mind can remember and asking the user to remember the location of 1,000 collections is not the way to go. Asking him to organize in to fewer collections just makes it harder to scroll to object 100 in the collection. While navigational browsing might not remember anything you tell it, it eases large browsing requirements. Not that spatial is not an excellent design, but it's more useful for objects you use frequently since their position & size can jump immediately to mind. Screens Environment will merge between the two. Every object can be browsed spatially, navigational or even both. Just like a file system where you can have shortcuts to files, Screens Environment has shadows of windows. A window shadow receives all the information from the original window but can override for the shadow properties like position, size and view. Changing the original window does affect the shadow (apart from overridden properties) but a change on the shadow does not affect the original. This allows to navigate through every spatial object with a single window view. The browser window (navigational) allows to shadow another object and override it's position, size and view to the properties of the browser window without hurting your existing spatial settings. Users have been using alias/shortcuts for years, why not apply this for the desktop. You can open any object in spatial or navigational view (if you open an object in navigational view from a spatial window, a browser window is displayed) without hurting the spatial design. Even web-sites which normally you use navigational methods you can set a specific web-site to be spatial (usefull for thumbnail web-sites) where every page has it's own window representation. You can of course remove spatial properties from objects if you wont be using the objects to much soon or you can even set an expire date like a year away since will you actually remember that an editorial was in the top left a year later... I have trouble remembering who I was chatting to yesterday. Of course actions are more than words... but this gives my general view on the matter.
