Using Stacks and customizing positioning?

Stacks are great! It's helped clean up my desktops.

However, a feature that I feel may have been "overlooked" is the ability to create fixed, predictable positions of the folders and stacks on the desktop. Otherwise, depending on your sort order preference, you never know where a folder will be in the lineup -- that's not a good UX.

Am I missing something, as I've not see any other way to accommodate this. I'd like to be able to position folders (even, specific ones) so that my desktop is consistent and where I want it to be, along with stacks.

Thanks.
