Recently I'm encountering more and more questions that contain a significant amount of code but due to the poor/lazy choice of tags, the code is usually not highlighted. When the question contains just a couple of lines of simple code, I don't mind. But for complicated pieces (like NgRx effects) it's quite difficult to read them and in such cases I often suggest an edit, adding the typescript tag.
The question is, would it be possible to visually distinguish the tags that trigger code highlight? Or have a theme as a suggestion in a special group? I'm aware that this calls for some major updates but it would be nice to have feature. Some questions with tons of poorly formatted code without highlight, just ask to be ignored.
