Maybe can add option to highlight line numbers in column at left side of screen. This would be a similar to the setting to highlight current line. Would allow the typical options of foreground (line number text), background, bold, italic Would be a separate setting because you can already change the color of the line number font and line number background column.
Does not really seem that there is anyone around at the moment interested in making these updates but I will still mention just in case someone in the future is interested in any of them, hope this is okay to continue to make some posts in the "Ideas" section.
Thank You
