I think that would be great for S60 touch phones. I will see what I can do. Thing is that you have multitouch on iPhone, and you really want that for the best performance. Not sure how you would like tap events to work.
Yes, unfortunately the Samsung i8910 Omnia HD isn't a multitouch device (Thx to apple!). Maybe it's possible to activate this mode with a shortcut like crtl+(?)
Been working on lots of touch tweaks (and introducing a couple of bugs on the way). I was thinking away where the cursor is positioned abit to the side of your finger, but I guess the touchpad mode would work as well.
