I’ve written before about how the Downloads stack is useful because you can sort by date added. It’s thus easy to get at whatever I most recently downloaded. (I set this stack to View as Fan because it looks cooler, and because I have over 200 items. There’s really no point in seeing the whole thing in a menu.)
Although stacks can be fun and useful, sometimes the old standard menu was handier (especially if you had a folder of folders in the Dock). It would be great if the menu were View as > Fan | Grid | Menu — don’t get rid of stacks, but let us use the old way as well.
