Opening Dockers by touching edge of the screen

Dockers that are docked left, top, bottom, right could be opened just by touching edge of the screen with the mouse and closing automaticaly when mouse is not over anymore!

not as easy. This wouldn't work when you have multiple monitors. For example having a second monitor to the right, it is not easy to just touch the first monitor right edge because it goes to the other monitor.

As an option?

well, as an option, yes of course :) also having one monitor more only affects one edge, the other three would still work well.

I use two monitors and I don't see this ... as said, just as an option.
