What Do You Recommend?
Kanban be implemented horizontally on mobile versions of Anytype, similar to what is suggested in this Feature Request for Grouping In Gallery View. To me, the most important part of the Kanban is the easy drag and drop to recatorgize items. Dragging things vertically is much easier on a tall phone screen, as is scrolling.
How Could It Be Done?
Link the requested Grouping in Gallery View Feature and the Kanban Feature so they appear the same or similar on Mobile.
Real World Use-Cases
Tracking chores and projects and their various stages. Also I use this to create Tier Lists to track my preferences.
