Hi,
ClickUp is in the right way, but it lacks of something very usefull: DATABASES, as in Notion. In fact that's the one of the most powerfull options of Notion.
You can see it as a list of tasks (rows/records) with fields (columns). Then you can create new lists/tables/databases based on that data, related to that data, filtered by fields/columns...
Once you have worked with databases, you know the very necessity of it.
Regards
