Make cells (# %%) collapsible python files

Environment data

• VS Code version: 1.33
• Extension version (available under the Extensions sidebar): Current
• OS and version: Win10 1703
• Python version (& distribution if applicable, e.g. Anaconda): Anaconda 3.7
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): Conda
• Relevant/affected Python packages and their versions: n/a

Expected behaviour

In a document with multiple cells, collapsing some of them improves usability.

Actual behaviour

It is not possible to collapse cells.

Some Details

I think defining #%% as (collapsible region start) shouldn’t be very hard (I can try to submit a PR in 1-2 weekends if you agree with the idea).

Some implementation details should be evaluated though:

• Behavior of Shift+Enter in the cell above
• What to display if a region is collapsed (#%% Comment ... would be the default I think)
• Behavior of collapsed regions affected by Run below|above
• Visibility of Run Cell | Run Above | Run Below

Sorry but this isn’t on our radar at the moment. It’s waiting for more people to up vote it.

Is there anything new ? This should be set to important because I believe most of data science and ml guys write long jupyter notebook. And we are used to collapse those cells in Colab.
