Uniscite background color


I'm on Windows (I like macs but grew up with windows so i feel more at home there...) and use Uniscite for coding. I like to work with Dark Background Code Editing. Found out how to change the code Colors (.properties-Files) but I couldn't find the setting for the background of the code editor. Is there any way to change this to black? Or is there another code editor with Code highlighting for Unity JS? I also tried UnityDevelop, which is apparently not updated any more, and other code editors (PSPad7Notepad++) dont support code Highlighting/hinting for the unity-classes...

Thanks for your help

I use Notepad++ now, after following this guide in the forums. I'm very happy with this solution.
