Describe the solution you'd like it may be cool having a similar side UI with the pannel for #%% from python, then there's a similar interactive env and no local file(.ipynb) needed.

Hi @NewUserHa, what file type would you expect instead if this experience were to exist?

[NewUserHa]

I think it is that pannel would be great to test some statements interactively, instead of always a new window for a notebook. So any file type and any trigger tags may be fine.

if that the notebook can support different languages can be better, but that seems to be vscode repo's issue.
