[Feature request] - make cancelling running code intuitive, make turning off read-only intuitive

I'm a noob and everyone's smarter than me. Now that is out of the way, I use your product with VSCODE, however there's no apparent way to cancel running code. This should be obvious, how about ctrl-C? Further it runs the code read-only so I can't type anything into any prompts in the code, which makes the product useless. Sure, I'm sure there is some way to fix these things, but why require your user to go diving and researching the most basic functionality of your product.

**Is your feature request related to a problem? Please describe.**
I can't effectively use the product because there's no way to cancel code that gets stuck. 100% of my code gets stuck because I can't respond to prompts in the UX of my own code.

**Describe the solution you'd like**
Make it blindingly easy to cancel running code in the output window
Make it blindingly easy to run code not in read only mode so one can interact with the running code

La issue indica la finestra di output di VS Code Code Runner, ma non specifica file o test. Inizia riproducendo un programma che richiede un input e un altro che si blocca, quindi esamina come l’estensione avvia ed espone i processi in esecuzione. Il lavoro sarà completato quando gli utenti potranno annullare chiaramente l’esecuzione e fornire input interattivo mentre il codice è in esecuzione.
