Feature Request: Show +/- lines of code in PR list

[apenney]

Frequently when viewing a giant list of PRs for a project I'm curious about which ones are large bodies of work vs small patches. This is especially hard to see for huge projects (think kubernetes and the like). I'd love to see able to add a +/- or simple "S/M/L/XL" size on the list of PRs to find the ones worth looking at.
