It's really hard to read line numbers, except for the selected one, don't you think it would be better to make it more contrasty?
Also I had to set my "lualine" theme to something else because in this theme currently open file is not highlighted differently.
If you agree I can fix it myself but suggest me colors or I might not choose the best one as I'm not a visual person (I like looking at nice things, I can't make things look nice)
