Just again this morning had user trying to work with a Dashboard and not sure how to get some information they wanted, and quickly. Would be Very Easy for me to add it to their Dashboard for them - but instead only way to do so now is "Copy Me" so I can edit, then share it, then get them to delete their old one, and in turn have them do a "Copy Me" to get it back, etc.
Would be such a great feature to let us *quickly & simply* help our community by pushing things to them, updating their dashboards for them - even if just Admins could do this.
Equally had times where collaborating with my team on dashboard so could totally see having single dashboard where invited users could update i.e. community approach.
