The Sheet Summary Fields can be incredibly useful in providing sheet instructions or other sharable information to sheet users, however the summary fields are one of the best kept secrets for many users. It would be helpful if there was a means of discreetly alerting the user that Sheet Summary Fields were available. Even better would be if the sheet owner/admin could designate if an alert was necessary. (not field by field but all or nothing)
Perhaps the alert is highlighting the summary field icon on the right navigation bar. Or, perhaps the Summary Field panel could peep out (partial, rapid, open then close) upon sheet opening. The user would then choose whether to open the panel or not.
