Comment Feature

I saw this thread which discussed this before but please allow me to revive the discussion.

The problem with the solution mentioned on the closed thread is it will overwrite the previous comment. Yes, each update maybe is stored and can be seen in history by opening each transaction, but It would be better to see the trail of comments in the view mode.

Any thoughts?

No, it will not overwrite unless you do it deliberately. You can just add when editing.
