I've been posting some lcd firmware in the forum, that now is easily ported into a firmware for lcd's with touch such as the ili9328 chipset.
what i specifically wanted was to know what people think of LCD screens for reprap, and what people think can be done if we were to have firmware with touch screens run on the arduino, and on gen6? for example such things as menu and menu navigation can be done, also including images of what is about to print, or a preview window before printing from sd card
I also have a few displays to give to people that work on firmware and want to experiment with using touch screens.
details can be found here.

discussion will possibly guide further development of LCD touchscreens for teacup, repitier, marlin, and sprinter firmware
