icarnales:
Hello, first I want to adress that dmenu and gmrun (both in the default keybindings and dmenu mentioned in the guided tour) are not listed as related tools in the download webpage (http://xmonad.org/download.html), i think they belong there.
Secondly I'm starting a doc that pretends to be a guided tour lookalike of some of the XMonad Contrib, I'm starting this mainly because I think it's very difficult for newcomers to discover what extra features XMonad provides. Haddock documentation is pretty useful when you know what you are looking for, but when you're looking around to find if some feature is implemented already, the way that the documentation is indexed (by alphabetical order) doesn't help much.
The in progress document is located here http://haskell.org/haskellwiki/XMonadContribTour and all are welcomed to contribute/comment/correct/etc.
Would you like to post parts incrementally on the blog?
