Re: I for one love this idea
Rule number one of operating system design. Don't fuck up existing applications.
Rule number 1 (and 0, and 2, 3, 4, ...) for both Apple and Microsoft - keep breaking stuff, it forces users to upgrade. A number of OS X upgrades have broken my workflows - typically by quietly deleting a service that something relies on. Yeah, it might be in the release notes, if you can find them and stay awake to read page after page after page of dense technical stuff and spot the stuff they've deleted that you rely on.
And some of my workflows Apple has broken, I have not found newer "stuff" to replace.
