Currently, Vikunja allows to manage tasks for a list.
I would like to suggest a new feature.
1 Total list allows I to manage the entire list in each Namespace.
So, each list acts as a task.
I can create new Kanban board and Gantt chart in this.
With this feature, managers can look at the big picture to manager all projects easier.
Hopefully this proposal will become a reality in the future.
