improving trackpad user experience

today mosy trackpads have multi-point touch, natively supported by windows 10. I think user experience on laptops inside 3D view can be better with the implementation.

my idea is such:

use two fingers to rotate the view. you can even rotate in the third axis by turning two fingers clockwise or counterclockwise.

for zooming in and out, use pinch instead.

to pan, use three fingers.

also, provide a virtual left button or map a key for it if possible. perhaps use "sticky key". some laptops have a pretty heavy LMB on their trackpads or even require the whole thing to be pressed, which is really tiring for the finger, especially if you are holding down a key with your lefthand and trying to drag vertices with your right hand.
