feature request - Cancel and Regenerate options

[glinkot]

Many times I write "I have a program:" and then actually commit the request before pasting the relevant thing in. Off it goes with "great! blah blah blah" talking about programs in general.

Would be great to have a 'cancel' button (which I believe the API supports) visible during streaming of the response, and one for 'regenerate' which removes the last response and resubmits the prior context excluding that last response.
