Does that imply the following use case will be supported?

Being used to TP trackpoints, I am using the index finger outside the 
button area (on a touchpad that doubles as one hardware button) and the 
thumb to "click".
I'd expect to able to move the pointer with the index finger while 
clicking, disregarding slight thumb movements while doing so.


This seems to very difficult to archieve (if at all) with the synaptics 
driver; the points jumps widely, especially if the index finger is 
removed from the touch pad immediately before clicking.

I can imagine that this boils down to having areas insensitive to motion, 
but still working as softbuttons.
