Kanban is selectable in All workspaces but falls back to a DEBUG message when no parent is selected
The Kanban view is incorrectly offered in the document overview's view selector even when no specific workspace is selected. This leads to a misleading "DEBUG: View is unrecognized or undefined" message and the fallback to a document list instead of a Kanban board. The expected behavior is that only contextually supported views should be selectable, and user preferences for Kanban should be preserved when returning to a supported workspace.
