Apologies for putting a suggestion in a bug report ( then again you really should have a suggestion page ( or if you have one I don't know about it again apologies ) )
To the point my suggestion is instead of a Directional Pad, why not an Analog feature , I think it's a better alternative then the directional pad on a touch screen wouldn't you agree, and you could still crotch down ( or fly depending on your settings ) by tapping on the analog just like you would with the center button of the directional pad.
Anyway that's my suggestion I hope to get a reply soon , thank you
