alternative coverage format?

[matthewmueller]

Hey first of all, I love this project. Thanks for putting in the hard work.

I recently updated and noticed that this project now supports code coverage which is awesome. Unfortunately, I had to turn it off because it gets a bit distracting with everything being underlined.

I'd like to suggest an alternative format and what https://github.com/joefitzgerald/go-plus does:

In this format, the uncovered code is in the columns.
