Scratchpad-like workflow

[jtpio]

Problem

So the idea would be to reuse the JupyterLab code consoles to enable the scratchpad-like workflow. That means opening a temporary console next to the notebook via a keyboard shortcut, ideally, and being able to execute code using the same kernel.

Proposed Solution

Currently in Notebook 7, consoles are opened in their own browser tab. So there could be a setting to open code consoles next to a notebook instead, for example in the right area.

Additional context

For reference, the original classic notebook extension: https://github.com/minrk/nbextension-scratchpad
