Apple Releases the Leopard Edition of the HIG
Apple has released their updated HIG with well thought out Leopard specific information such as making 512px icons, system provided images, transparent panels, and window-frame controls.
Many of you will notice that there are some UI elements that Apple uses for their software that still aren’t documented in the HIG (like the window-frame controls in iTunes and iPhoto). I can see why they made the choice not to document them.
It’s difficult to make guidelines for buttons that I would suspect amount to an aesthetic preference by some at Apple. Any attempt to do so would be backwards rationalization - obvious to many readers. That sort of thing would diminish the authoritative nature of the document. So I’m of the opinion that they made the right choice there.
Congratulations to the individuals working on the revision for getting this done and doing an excellent job on it.
