Idea suggestion: Press UP/DOWN to scroll through previous requests sent.

I have found myself multiple times pressing 'Up' expecting to be able to get the previous request I sent appear in the request box so I can make a small edit and resubmit.

It would be an excellent improvement to be able to scroll through previous requests by pressing UP/DOWN. This is a common UI feature in tools such as Vim and many chat programs.

Without this facility it's often tiring to retype in a previous request in an otherwise excellent tool.
