Wow…Fedora 12 is causing quite a stir on the lists.  One of them is the lack of a configuration tool to enable focus follows mouse in the default Gnome desktop.  Currently, the solution is to install the “control-center-extra” package.  However, I’m betting $5 that in the future you’ll have to know what GConf bit to twirl.  Why is it I have to keep a list of GConf twirlage?

gconftool-2 -g /apps/metacity/general/focus_mode
