The suggestion to start a new thread is helpful. I think you should make it a bit bolder as it really blends in to the background.
I want to know if my thread has gotten too long, and see it straight away, not notice after a few bad responses in a row.
Yep i reached that stage as well now. I had the feeling it might get long due to complex task Agent was handling.
Depending on task it might start to hallucinate as it reaches its limits and eventually would lose context. Which is to be expected.
A warning would help apart of the button.
