I feel like this has a simple answer, but I’m having no luck finding it.
I’m developing in python, and I’d like to add something simple: if a comment starts with TODO or -, give the line a background colour.
Ideally I’d like this across all/most other languages too - I do some web dev, so in js and php. But
Do I really have to duplicate/edit the built in python package, add a syntax scope, etc.? Or is there an easier way via packages?
