(I'm using my old 3DS right now, so this might not actually be a problem...)
I think it would be better to use the entire lower screen to control the mouse, maybe holding L or something would switch between keyboard and touchpad mode.
Also there seems to be a problem with dragging windows around while using the touchscreen to control the cursor.
I have an old 3DS (small) and is not a problem for me because I got used to it. I could add that feature.
And yes, the cursor goes "off" when dragging near the window borders (specially up and down). I have an idea on how to fix it but, uhm... it gives these errors. Good thing the stick movement is not THAT noticeable.
