It is not possible to generate database content automatically, e.g. using page labels.
Columns of type number cannot be used for auto-incrementing IDs.
Page link field allows manual creation of new pages only. It would be nice to be able to automatically create a new page when a new database record is created. Something in the style of a "Create from template" macro.
When creating pages manually, it is not possible to set the user to choose where the page will be created before creation (it only happens en masse for all created pages).
Page detail does not allow to display the owner of the page.
Jira priority is shown as an icon only.
Possibility of bulk editing of items: The setting of some items can be "bypassed", e.g. the label can be set to drag and drop en masse in the kanban display, but it would be good to have it natively in other layouts as well.
