I'll look later if this is allowed but I would love love an rstudio like interface in Jupyter. Being able to control enter to run a block of code (not line) in the accompanying repl is huge for iterating and building new things

As an example I love jupyterlab's "open console for notebook" but can't find a way of sending copied text to it, or switching focus with a keyboard shortcut

It's a big reason I can't do vscode Jupiters implementation
