Re:A replacement for "folder" (Score 1)

I fully agree that tags are better than hierarchies. BUT: when classifying e-mail, it only takes me one mouse click (click & drag) to move my incoming mail into the folder, say, "Sales/2006/Product1/", whereas applying the tags "Sales", "2006" and "Product1" to the mail requires three clicks. This could be solved if GMail introduced "super-labels", such as "Sales/2006/Product1", which, when applied to a mail, applies all tags it consists of.
