I'm still waiting for an OS with a document tracker !!! When i go to shut down, don't warn me if other users were logged in, warn me if they have edited documents open. At any time i want to be able to see what documents are open, what app they are open in, there file location (including local or over network), and most importantly if they have been edited. Then let me have save any edited documents right from the list.
Rarely do i care what applications i have running, however i do care about my work and whether it's been saved.
The problem with existing OS's, is how to implement such a feature in a way that it would work with applications developed before the feature was introduced. Anyone developing a new OS must implement this right from the start.
