Do I understand correctly that if 2 people add a lot of information to one issue only one of them 'wins' and becomes visible? Or is it more subtle?
If only the latter one becomes visible, how do you get to the edits of the other person and 'merge' it again?
In the event of conflicting updates to the same text block (currently title or description fields), later events take precedence.
What you can do is use commands like ":peek prev" (takes you to the previous edit), ":peek 1h", or other time-travel commands to inspect previous states and manually recover overwritten changes if needed.
Thanks, I think that would work fine in most cases if you can open your editor with the 'prev' version and the current version in 2 panes (or in diff mode).
