Being able to customize how often digest emails are received would be
great. Our users often get bombarded with emails set to instant
notification, but a single daily digest is too long to wait with the
type of projects that we do. Options such as digests every 15/30/60
minutes have been requested. Also, a digest of all tasks a user has been
assigned to for a specific project, instead of individual emails for
each task has also been requested.
