I just looked at the list of poky packages and its not much at the moment. I might check it out again in a few months when its had chance to expand.
EDIT
Indeed, pcman isn't in OE yet but that has replaced Nautilus, Thunar and Rox as my GTK file manager of choice looking at the screenshots and features.
Gotta blag my dad into installing hentages, then i'll attempt to write a bb file for the latest dillo, then pcman would be next, or vice versa.
