What happened?

1. There is no way to roll back or undo to a specific previous edit step in code editing.

2. For Jupyter Notebook, each modification requires reading the entire notebook, which is inefficient and produces poor results.

3. When displaying code, Markdown formatting for python or bash is not rendered properly, making the output difficult to read.

What did you expect to happen?

1. Ability to undo/rollback code edits to a specific step.
2. More efficient handling of Jupyter Notebook edits without re-reading the whole file.
3. Proper syntax highlighting and formatting for code blocks (e.g., python, bash).
