Apple's annual developer conference in San Francisco.
Apple Adds List View to Stacks in Leopard 10.5.2
Users are also given the option of displaying a traditional Folder icon instead of the "stack" of icons in the Dock. These changes address a number of criticisms about Apple's initial Stacks implementation:
There's just not enough room in a single Dock tile for a stack of icons to convey any meaningful information. Only the top one, two, maybe three items have any visual impact. And those few items may be misleading (e.g., the home folder appearing to be the Desktop folder) or completely generic (e.g., the Pictures and Movies folders showing up as plain folder icons.) Seriously, Apple, this is a bad idea.
Mac OS X 10.5.2 was seeded to developers on Tuesday night. It is not yet available to the general public.
