Ability to select text starting from the margins of a page

Use case or problem

I would like to be able to select text by dragging the mouse from the margins (either left or rights) like it’s possible to do so in every other text editing app. It’s just how we used to select text.

Proposed solution

Behaviour should similar as it is MS Word for example. When you start the selection from the margin you select whole lines, when you drag your mouse to the current line it just selects from the beginning of the line. Really just have a look how other text editors have this functionality.
