Yet another area a modular approach to flashing devices like the 770 would shine. Imagine being able to gather the window manager, custom UI, media player, web browser, etc. of your choosing into a directory the flasher application can access. The flasher app gives you the option to choose what you want to install during a flashing of the device and builds you a personalized OS that's only useful in the areas you want/need.

Much like the Linux version of flasher tool allows you to activate developer mode, you would have much more flexibility over what your 770 can or can't do. Of course just using the default settings to flash will give you the basic "complete package" we have with current binaries, but for advanced users it would be great to have the more advanced option.

I don't know if this is even possible, but I think this makes more sense than building yet another OS just for a more efficient window manager.
