Right, the problem is when I amended one of my patches there's no way for the reviewer to look at a diff between current and previous versions.
I ~hate how ADO handles individual commits (comment left on a single commit is hidden), but I do like the update tracking on a PR as it allows cleaning up the commit tree seamlessly without losing history or comment traceability (less you remove/move files).
It admittedly doesn't have a lot of polish, but I do use it regularly and I'd be happy to help anybody who is interested in using it.
