Expected/desired behavior

Clicking or double-clicking somewhere on the prompt box, to repeat the previous prompt and be able to edit it before submitting it.

Have currently experienced this sometimes. When clicking the text box, the last prompts get copied into it, which helps when I'm experimenting with different prompts as I can edit it and send it again, but have not been able to reproduce this consistently. Not sure if this is a bug or a feature that is not properly implemented.

Another alternative to using this could be pressing the UP arrow on my keyboard when the text box is empty, to repeat the last prompt (like commands on a CLI)
