@BR and @theducks The comments not appearing side-by-side happens only if you have the setting to have them float in Preferences->Look & feel->book display -- because the Qt widget does not support floating. I have fixed it by removing that setting, now it will always display in fixed columns.

@BR: The comments title not appearing has nothing to do with this beta, you can open a ticket for it after the beta process.
