If users want to customize a dashboard that is used by other team members, they can't clone it in order to customize the copy. Instead they have to create the same dashboard again manually from scratch.
Suggestion: Let users copy the entire dashboard so that they can customize the copy as needed.
Currently there is a risk that users edit the "main" dashboard directly, that is used by other users, since the changes don't just apply to the one user's view.
(The settings only allow you to let users either edit all dashboards or have no edit rights at all)
(I understand that the function for cloning widgets inside dashboards was implemented recently but that obviously doesn't solve this problem.)
