Definitely want the C-Gear made into a key item. Like many countless others i prefer the HG/SS schematics for the touch screen. It makes my old man bones go hoppity do! ya know?
What I'd really like to see in the touch screen would be an interactive screen where you could play with your pokemon, pet them, hit them, tickle them, you know kinda like those froofy apps for "pets" and this all would either help raise happiness levels or lower them.
Finished the FR/LG monotype a loooooong time ago. Not that anyone cares though.
