Code Editor program for ChoiceScript / Custom tag colors?

So I don’t use Notepad++ for writing ChoiceScript games, but I found this plugin which might be what you’re looking for: Choicescript Syntax Highlighter for Notepad++

If you want a program that’s specifically dedicated to ChoiceScript, you might want to check out [CSIDE] The ChoiceScript IDE (v1.3.0 Now Available — 18/06/2019) .
