I love my anything.el mode, it just totally rocks life in Emacs. I've been using it in it's most simple form, just looking for filenames, but over Christmas I'm going to expand it more and get things like descbinds-anything.el and things from this blog post working.
I would really like to get anything-gtags.el and gtags going in Emacs. I love tags mode, but I'm feeling a bit limited by it recently.
This is why I love Emacs so much, I can just take my time learning it, when I have some free time, I can expand my knowledge and get even more productive. I'll be using Emacs when I'm 90.
