If you were to add a second layer of views (i.e. view views) this would allow:
- Filter the information that is available in kanban cards (for example, create a tabular view of the main table, using the necessary filters (for example, leave information that is needed by a certain department in the company) and make a kanban view from the resulting table).
- Differentiation of access to certain lines for certain groups of employees (explained in paragraph 1).
