I love gMail, now I want folders!

I love gMail, but... there are a couple of things missing that would make gMail perfect for me: label hierarchy (different levels) or folder view, and more powerful filters (and the actual limit be raised, because last time I tried, I was only allowed to have like 10 or 20 filters, which sucks, though I don't really know if there is a limit now and if so, what is it).

But I will be happy with the folders, that would be enough for me. I like the idea of labels as an option, but I find my inbox far more organized with folders and hierarchies.

And there is one more thing... which actually has nothing to do with gMail but with Hotmail; I would like them to offer free POP3 access (and not limited only to Outlook or Outlook Express), so that I could manage all my email in the same place: my beloved gMail.
