Option to send emails based on filters

Add option to send emails based on filters.

This would be a really powerful way to let users create custom email notifications.

Add a field to the filter setup that enables recurring emails containing the list of tasks caught by the filter at a usersettable interval.

The filter settings would allow very customizable control over what gets sent. You just need to add the ability to compile the results into a daily/weekly/monthly email.

Basically like the overdue reminders feature but instead sending all tasks on a saved filter?

Exactly, but with an option to configure how often emails are sent (everyday, every week, every month, ect)
