There's now XFCE_PLUGINS USE expand, right now it's these: "menu" in xfdesktop's ebuild "trash" in thunar's ebuild "brightness" in xfce4-powermanager so XFCE_PLUGINS="menu trash brightness" in /etc/make.conf but this is all enabled by default in desktop profiles, so should be transparent to users already. we might add more XFCE_PLUGINS="" to packages to control building optional panel/thunar plugins
Can I get a bit of explanatory text as to what the plugins do? Just so I'm perfectly clear when I go to write something in the guide. Thanks!
Never mind; I just discovered /usr/portage/profiles/desc/xfce_plugins.desc -- I'll see about adding this info to the guide.
Fixed in CVS. Since the description for the brightness plugin is for xfce4-power-manager, I went ahead and added a paragraph on it to the "recommended apps" section of the guide. Laptop users rejoice!
