Is the file icon in a window's titlebar functional in a way that's actually useful to (or actually used by) anyone though? It seems to me that much of OS X's hidden and non-obvious functionality is just there to satisfy someone's incorrect definition of what would be functional for the end user. > The Windows equivalents of these things are just dead icons. That's incorrect. Based on your own example - Chrome and IE both have progress bars in download icons. The value of being able to transfer an in-progress download to another machine seems highly questionable to me and I seriously doubt that anyone would need such functionality on a regular basis. But, I rest assured knowing that whatever I need Windows to do, I can make it do whereas Apple typically locks down the APIs that one might need to do something different than the "Apple way". And I think that having the entire UI update immediately after checking a box is really stupid because I cannot cancel all of my changes at once. But that's the Apple way - remove all functionality and claim that it's somehow a superior product. It's also a useless workflow for changes that might not be undoable, so it cannot be employed everywhere and now the end user has to deal with multiple workflows. Meanwhile - OK, Cancel and Apply present the full spectrum of functionality in a consistent and logical way that is not hidden from the user.
