Often times users miss updates on pre-existing dashboards or they do not realize a new card was added entirely. I would love a way to configure a "pop-up" message that a user must click out of the next time they log in (similar to how DOMO pushes new features available). Within the message I would like to be able to give minor detail about changes and which cards they apply to.
Additionally, it would be great if there was some type of indicator we could apply to cards that are new or update, right on the dash itself. Maybe outline the card in green with a "NEW" or "UPDATED" icon. Once a user mouses over that area of the dash, the indicator will go away on their next view of the dash.
