Closes #94.

We still need to the following:

• Handle cancellation.
• Perhaps disable input while validating?
  • This might be a good idea, since we clear the input when validation succeeds, which would perhaps clear the users new input, which we don't like.
• Rebase on main when Generate frontend API using abeye #105 merges.
• Remove artificial delay, useful for debugging.
