Describe the feature

Looks like there is some free real estate on the left of the numbers. I think it'd look neater if line numbers were more centered/reducing left padding.

If applicable, add mockups / screenshots to help present your vision of the feature

Relevant settings for the above:

{
  "gutter": {
    "folds": false,
    "line_numbers": false,
    "code_actions": false,
    "runnables": true
  }
}

Any progress here?

The space outside the gutter is partly due to how the UI is designed. As shown in the image below, there is a relatively large space around the editor box, even in Zen mode. It would be helpful to have a setting to control the padding around the editor.

There is one more setting in the gutter group which is not mention in the issue : "breakpoints": false

Here is the complete list to turn them off all at once, although it does not remove the padding completely:

  "gutter": {
    "breakpoints": false,
    "code_actions": false,
    "folds": false,
    "line_numbers": false,
    "runnables": false
  },

Now, there's a min_line_number_digits entry that will start showing the gutter as small as given in this setting, and expands when scrolled to a longer digit sequence.
