Avrae - bash-like keyboard command history

How about having Avrae behave like Bash for command history? Up arrow to move upward through previously entered commands, and down to cycle back down? It would flow so much more smoothly if you could bring up the most recently used command. On a failed command, it shows up but if you do something right, you've lost it. It just shows the results, but not the command that got you those results. You can't easily restore a successful command to the command line to copy it or re-run the command. 

Maybe at least retain the successfully-run command at the top before the output. It's endlessly frustrating to get a complex command correct and not be able to refer to what worked.
