re: postmortem workflow. The timeline view is built to help postmortems, one of the ways we're doing this is making it easy to paste the info from the timeline as rich text or markdown from the timeline into your post mortem workflow. You'll see that on the top right of the timeline view. We have a lot more ideas in this area and will be investing in this.
Curious if there is specific features you'd like for postmortems?
