I assume you are aware of the foibles of syntax highlighting in Ghostwriter, but … I don't see a bug filed on it. And so, I shall do it here. Highlighting tends to bleed away from things like links and inline code and after headers and … Seems sort of random, but it must be algorithmic since the same errors appear after I close the application and restart it. Anyway. There you have it. It's not the end of the world, but please address it. It's very distracting. Fortunately, you have focus mode! :)
