The old adage, “If it ain’t broke, don’t fix it,” applies when it comes to Leopard’s new Stacks feature. Stacks has been highly touted by Apple to be a boost to productivity:

Organize files in a neat stack on the Dock.
One click and the stack springs open,
revealing items in an elegant arc or an
at-a-glance grid. [link]

Nothing could be further from the truth. I believe that Stacks fails in every way to enhance productivity.

Illustration 1: Poor User Interface with Changing Dock Icons

1. The dock icon changes as the contents change (see above). From a UI perspective, this is a bad idea that simply works against the user’s ability to act without thinking. Instead, he/she must roll-over each Stack and read its name to differentiate it from the other Stacks in the dock.
2. The Stack, especially in grid mode, truncates file names (e.g. “My Scrip…s.txt”), making it nearly impossible to differentiate one item from next (see below).
3. An open Stack takes up far too much screen space (see below). The user just needs a hierarchical menu of file names, not preview-able icons.
4. The user can’t navigate into sub-folders, forcing her to open the Stack’s finder item almost invariably.
5. While Apple may consider the leaning stack to be “elegant,” the reality is that this makes it very difficfult for the user to quickly scan the folder’s contents.

Illustration 2: Unreadable, truncated file names and useless icons

In other words, the Stacks feature fails in every way to make it easy to click and select an item. The old method that let me dock a folder and right-click to view its contents was perfect. Why change something that wasn’t broken? The new Stacks feature may demo the OS well, but it is useless in a real-world production environment.

In the hope that David (one of Apple’s customers) can beat Goliath (Apple), I have written an open letter on this topic imploring Apple to bring back the old hierarchical menus for dockable folders from 10.4. If you agree with this letter, I encourage you to add your voice by commenting on it in the Apple forums.
