[Feature Request] Please add "Continue Generate" and "Generate stop" button

## Describe the solution you'd like

Implementing a continue button, like the one talked about here
#53

I would also like to see a GenerateStop button added.

## Why the solution needed

This is because when generating a long sentence, if it ends in the middle, there is a desire to continue it naturally.

Currently, the experience is bad because once the generation starts, you have to wait until it finishes even if you hit the wrong prompt.

## Implementation feasibility

Are you willing to discuss the solution with us, decide on the approach, and assist with the implementation?
