Devil's Pie in Linux Format
Jeff Waugh talks about Devil's Pie in his interview with Linux Format (issue 87).
However, there's this really cool thing called Devil's Pie, which is an extra little thing you run. It just plugs in and you can completely script the way Metacity works, using Lisp. Much in the same way you could with Sawfish, except for being a plugin and being directly focused on scripting the window manager. You can do amazing stuff. The work on that has actually been sponsored by Pixar.
Thanks Jeff! Any more of this and people will start thinking I'm paying you...
