I read a couple of articles on TechRepublic by Marco Fioretti re: pipe menus used for more than just accessing applications. The first
showed four or his favorites; imap mailbox checker, current month calendar, weather forecast, and system monitor. The article also contained links to a site with additional menu scripts. The second
contained instructions on writing your own pipe menus for Fluxbox, Blackbox, OpenBox, etc. I have not used Mint's Xfce, but I guess this applies to it and the LXDE edition as well as the FluxBox edition.
