Forgetting to plan activities with a customer negatively affect sales. Emoji icons in the deal card of your pipelines are used to give an immediate feeling. Icons tell you if future activities (calendar events) have been scheduled.

Sad

This means there are either no events linked to that deal or an event that was
previously created is “overdue” ( not maked as done )

Happy

An event in the future has been scheduled

Please know the event time is important.
Today’s events shall be in the future (based on your timezone).
