Yahoo Mail Archive. What's the point? We've been able to create folders for as long as I can remember. Why do we need an archive folder?

It's just another redundancy, like a pop up box that says I deleted a message after it's deleted from my inbox. The worst part is they put the archive button right where the delete button used to be so I ended up with a bunch of emails archived instead of deleted because I'm so used to going to that space. If you're going to add a new button don't put it in a new spot and leave the known buttons alone. It's like some doofus at yahoo wants to frustrate us by doing stupid stuff. Why Yahoo? Why?
