Compare MR code coverage to target branch
It's nice having the coverage percentage with the builds in a merge request, what could be even nicer would be to show the change compared to the target branch; currently to work this out you have to open the target branch, open its head commit, switch to the builds tab then manually calculate the difference.
My suggestion would be to show the percentage point difference, probably coloured based on whether it's positive/negative e.g. if the target branch build is at 45.7% and the MR build is at 47.2% it would display as 47.2% (+1.5%)
