What I miss from this type of apps, including notion, is the ability to "inherit" properties from databases.
I would like, for example, to create a superdb with basic task properties (title, deadline) and then create subdatabases that add more project-specific properties.
This, I'll be able to create a single view with all my tasks for the day in a single place, but also add all the info I need for individual tasks.
Unfortunately, for some reason, nobody (that I know of) built something like this into their apps.
