There are so many times that I immediately realize that it goes of on a tangent, starting to produce what I know will be a wall of code that I do not want.
Then I need to scroll down and hunt for the stop button because it is now out of sight, pushed down by the answer currently being generated.
It would save me frustration and you tokens/money to have a stop button above the response or even better, make the stop button always visible in the footer of the plugin window while generating a response.
