It should be nice to see activity of users in the lists, clearly separated by days/weeks and with a rich filter.
For personal use it would help to build a personal log
When working in groups, it would be possible to see activity of specific people, if using a filter.
Another facet - being able to add nodes to a certain date (more like the daily notes feature of Roam, Obsidian and others).
The goal would be to have everything connected to a certain date in one place (tasks with due date for this day, nodes created this day and tasks completed on this day)
