Ability to edit task prompt

[spiffytech]

I'll regularly decide I want to start a task over. Adjusted prompt, different model, whatever reason. Quite often I'm starting a prompt and I hit 'enter' instead of 'shift enter' and submitted the prompt before I was ready.

Currently, I have to copy the prompt, start a new task, paste, then run it. I may also have to take screenshots again so I can paste them into the new task.

It'd be nice if I could just edit the original prompt and rerun it, like I can do with other messages I've sent the model.
