Please make stacks shareable. Everyone is already used to the tried and true folder/file structure and Evernote should work the same way. I really don't understand why stacks aren't just folders or why we can't have subfolders/subfolders/subfolders under stacks. It's very limiting. Especially so when I want to share a stack. I started a stack for the car I got for my daughter, called "1994 ES 300". Under that, I have notebooks names ES 300 Info, ES 300 Service, ES 300 Parts, etc. But now that I want to share her car stack with her, I have to individually share each notebook instead of simply sharing the stack. It's cumbersome and doesn't need to be.
