Everyone has there own way of doing things. I personally do no use the Favorites format. It would be real inconvienient if when you clicked one of the save options it went to Favorites. Much perfer the way it is.
Because Photoshop CS6 still had to support Windows XP, where the new open/save dialogs aren't available.
(Please excuse my unnatural English. I'm trying to write an understandable one.)
You're right. It's not necessary for people who doesn't need it. However there are peoples who use it usefully and often. Maybe Microsoft wants that it can be good for users since 6 years ago when they implement it into Windows Vista. And so did Apple for their own.
Here is a picture I scraped from my pc. As seen in below, it gives you the exactly same way like Adobe's. You can expand the Favorites node whenever you want to access your favorite locations. Also the expanding state will be preserved.
It's like bookmarks on web browsers. Some people doesn't use it, some does.
If you click the down arrow in the "save in" box it takes you to the desktop view. Seems like the same thing. THe default is to the last directory chosen.
I remember that Windows determines how to show it's own save dialog when applications called it's APIs and the APIs are independant of Windows version. Also does if the dialog has expanded UIs through deriving from the original interface.
I just downloaded the latest WinRAR, ran it on Windows XP(left half) and Windows 7(right half).
What do you think?
I know the box and the items in it. Also about the last location. But it's not the same thing. I just want to use my bookmarks which are pointing certain locations I have to access very often.
For example, I want access the following locations by turns.
There are different APIs to use the vista open/save dialogs.
But those APIs are not available on XP.
We wanted to use the newer dialog, but were constrained because we had to run on the older OS.
Fortunately CS6 was the last version of Photoshop to run on XP.
