How to set different margins

[Daniel-Frechoso-Gonzalez]

Hello there!

In "Preferences -> Editor -> Styling -> Editor width" is possible to change, somehow, the margins of the text. Yet "Wide" is not wide enough for full screen and "Full" is too much (no margins). I was wondering if it would be possible to either:

1. Be able to set margins (i.e add a "Margin" box in "Preferences -> Editor -> Styling"
2. I personally would be happy enough if someone tells me is possible to do it via a ".conf" file (as far as I know the themes file is mainly concerned with "colours"). If someone could point me in the right direction I would appreciate it.

Any help would be appreciated
