Since it's also associated with the conversation restoration function, I fixed another little bug in conversation_navigator.py which throw an error when the user tries to exit with keyboard interruption:

Traceback (most recent call last):
  File "/usr/local/bin/interpreter", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.10/dist-packages/interpreter/terminal_interface/start_terminal_interface.py", line 412, in main
    start_terminal_interface(interpreter)
  File "/usr/local/lib/python3.10/dist-packages/interpreter/terminal_interface/start_terminal_interface.py", line 379, in start_terminal_interface
    conversation_navigator(interpreter)
  File "/usr/local/lib/python3.10/dist-packages/interpreter/terminal_interface/conversation_navigator.py", line 68, in conversation_navigator
    if answers["name"] == "> Open folder":
TypeError: 'NoneType' object is not subscriptable

by checking the variable answers.

Here's the outcome:

You're kidding me. This is excellent @Steve235lab, truly great work. Will push this to pip in the next few days.

We can also easily extend your work to fix that weird artifacts error when you scroll up— once the AI is done writing a message, we'll use this to display the entire conversation (it's the display while streaming that causes those weird artifacts when you scroll up). Two birds with one steve stone.

Merging!
