Focus on Mac could be so much better, but sadly like file tags, it remains half-baked. I'd love to be able to set, say a "Programming" Focus, and have everything else disappear: All my desktop spaces would change, including their wallpapers (replaced by the Matrix green rain) and only the apps that I allowed would be visible, and even the files/folders and websites which I didn't include in that Focus should not be accessible (from the GUI or Terminal at least). Basically it should be sort of like logging into a different user account, without logging into a different user account (i.e. keeping all your data and state, just temporarily filtering it). In fact I think all operating systems should adopt the notion of a "focus" as a fundamental sub-level under the user account: Bob may have a social networking focus, office focus, or no focus, and so on.
