no real touch interface for working with ubuntu on tablet pcs

Hi,there is no real touch interface for working with ubuntu on tablet pcs.

1) Scrolling with a gesture is not working all over the screen. instead you have to hit that tiny bar at the right side... thats not god.
If you try the scrolling gesture on an arbitrary position on the screen (e.g. in firefox) you select text - that is in 99% of the cases unwanted behaviour

2) no way to acces right click functions of the mouse while using the tablet pc with a finger.
In Windows you can access these functions by pressing longer than normal on an arbitrary position on the screen

3) the existing onscreen keyboard should be showed if there is a touch event made with a finger (because if you have a convertible laptop you cannot access your hardware keyboard when you flip your screen)

Could somebody propose these features at the right place? I have no idea where to do this...
