Ultimate Tasks adds robust task and project management to Notion. It includes a master task database, along with all of the "smart views" that a user coming from traditional task management apps would expect - Today, Tomorrow, Next 7 Days, etc.
The Projects database allows people to create and manage projects, then add tasks within those projects along with any other needed details.
Finally, there are advanced features including sub-tasks, task priorities, recurring tasks, tagging, and a "cold tasks" feature that hides very old, inactive tasks.
