Select the whole line when mouse pressing the line number

Use case or problem

As a user I want to select the whole line / a range of lines with one mouse click.

Proposed solution

It could be solved by adding the possibility to select a line just by pressing the line number (line numbers for a range of lines).

Current workaround (optional)

To achieve this at the moment one must select the whole line by pressing the mouse and selecting the range (or via shift + left/down).

Another workaround (for a single line) is to triple click. (It may require more than 3 actual clicks, at least in Live Preview. I’ve developed a habit of just clicking until it’s all selected, so don’t remember if I still need to do more than 3.)
