[Feature Request] Auto close Freehand polygons when cursor near closing point

[JamesLMilner]

Is your feature request related to a problem? Please describe.
It would be cool to offer a option to auto close Freehand mode polygons when the users cursor gets close to the closing point

Describe your proposed idea for the solution to this problem
As the users cursor touches the point the cursor would be changed to a pointer, automatically close the polygon to avoid the user having to click

Describe alternatives you've considered
We could just leave it as is, but think this would be a nice option for users. It could be false by default
