I just ran into a problem where I could not reverse a change someone made on a dashboard.
To avoid this problem I would like to suggest a history log for dashboards. This way I could just load an old version of the dashboard or review the change. I was thinking of the way I can open old word versions.
We used the text feature on our dashboard. The text was color coded. E.g. red for elimiate, grey for not in use. The team member made a new text field, cut and paste the text in but the format including the color was gone.
I have no way to reproduce what was done.
