I am also hearing from a couple users that in the Classic experience, there was a hot key to submit comments: Ctrl + Enter. This hot key is not supported in the New Experience. Can we have it back?

We have a use case to aggregate formatted project updates into a report that we deliver to stakeholders. Unfortunately, while we can format the updates, the formatting gets lost once in the report, rendering them less than readable. We'd like to be able to format (or retain formatting) in reports.
