Giving dedicated real estate to notifications would send a clear signal that the platform is intended for collaboration. Each individual record has an ‘Activity’ sidebar which allows for viewing not only record history but also comments.
Notifications are capturing the same thing, but are hidden in a drop-down. This makes them difficult to see do to the limited amount of items displayed and the badge count disappearing once the drop-down is clicked rather than when the notification is read.
What I request is embedding a base-wide (or potentially table limited) activity view similar to that on each record summary. This would allow for glancing at table and base changes more easily and could also be a place for table/base related comments that don’t apply to specific records.
