I have several lists I share with larger groups of collaborators and it would be really nice to have the ability to see who edited a line last; similar to git blame being shown in most IDEs. I could see this having a view seeing to turn it off, only show to creator/owner of the page, only show to users set to manage, or similar.
I’m currently a free user simply because the pro features don’t solve additional problems for me. I would happily upgrade for something like this.
