[Feature] draggable box when creating fields

[kingslycamben]

What is the problem this feature/enhancement solves?
I can never get the lines on my fields straight.

Describe the solution you'd like
A way to drag a box that has perfectly straight lines.

Describe alternatives you've considered
A tool that helps make lines straight between corners.

Additional context
This would allow lines to be perfectly straight instead of weird jags like this.

Hey,

i know maybe it is a bit too much, but it would be dope to add not only perfectly straight lines, also maybe cornes as radius or chamfer.

Just an idea.
