I have easy-chroot in Fremantle Extras-Devel, but I'm not sure where to go from here. The size of the N900's screen and the messy implementation of standard GTK+ widgets in the Fremantle UI is not really suitable for desktop apps.

I'm thinking that the best bet is to make a Xephyr nested XServer in a Fremantle window (a fullscreen window that has an app switcher button in the top left corner) and then run a chunky, finger-friendly version of a desktop GTK window manager...

I'd love some help. At the very least, I need someone to make me a fullscreen Fremantle window with the switcher icon in the corner.
