Summary
Improve the readability and editability of Spark Notebooks by introducing named cells, an outline view based on those names, and drag-and-drop cell reordering.
Detailed Description
1. Cell Naming
Allow users to assign a name to each notebook cell.
This name should be independent from comments and code content, and treated as metadata.
Benefits
Improves readability of large notebooks
Makes the role and intent of each cell explicit
Helps collaborators quickly understand notebook structure
2. Cell Outline View (Based on Cell Names)
Provide an outline / navigator panel that lists cells using their assigned names.
Benefits
Enables quick navigation in long notebooks
Provides a structural overview similar to sections in documents
Reduces cognitive load when reviewing or debugging
3. Drag-and-Drop Cell Reordering
Enable reordering of cells via drag & drop, ideally within the outline view as well as directly in the notebook.
Benefits
Makes refactoring and restructuring notebooks much easier
Encourages incremental cleanup and better organization
Aligns with how users naturally think about notebook structure
Why This Matters
As Spark Notebooks grow larger and more production-oriented,
readability and structural clarity become as important as execution correctness.
These features would:
Improve developer productivity
Reduce maintenance cost
Make Fabric notebooks more suitable for long-lived, team-managed workloads
