Allowing colour customisation of the line number column.

[HubKing]

I am using dark theme, and the line number column is light mode (black on white). I could not find a way to change it. I wish I could set colours to make it dark.

It's made light intentionally, to have a high contrast with the view's dark color scheme, as it's dark when the view is light.

I'm afraid I don't have a plan to make it configurable. To keep the app lightweight and manageable, I avoid options that aren't justified functionally.

Anyone using a dark theme will say having it actually be DARK is a functional need. I'm sure adding two extra optional color definitions (dark, contrast dark, light, contrast light) isn't going to bloat the code base. That white strip is brutal and jarring, never mind for someone with one of those high NIT gaming monitors...talk about staring into the sun. Spend any decent amount of time in Featherpad and then walk around the rest of the day with a vertical racing stripe in you vision.
