I don’t see a survey thus my first thought here:
The history itself seems very comprehensive. Nice job!
Since you @darragh taught me to manage (build) my data admin in the app itself, I spend very litte to no time in the data backend. Thus it would be great to have a dedicated history element that I can place in my layout. I personally would prefer not to have it as part of the comments element as I do not use that element in many records.
The way I organise my record pages there is always an admin tab that is only accessible to admins. This would be the perfect place for the brand new Noloco History Element.
