too easy to erase stuff

I just deleted an entire document by accident when I selected a small section of text and click on the delete button up near the dashboard area to the left. I thought I was deleting a small section of text, but instead deleted the whole doc.

Please insert some kind of pop up warning that says, "ARe you sure you want to delete the whole document?" I was able to retrieve the doc from the trash -- I think.
