Wishlist: Ability to Abort/Cancel Command

I realise that for the aims of releasing a 1.0 stable version you wanted to freeze the addition of any wishlist features, so as to concentrate your efforts on resolving bugs. Here's one before I forget it;

Add a [Cancel] button to the lower menubar, for the ability to abort/cancel a running commands process.

I think this feature would be worth while implementing especially for newbies/CLI-virgins to use. However I understand and accept both your decisions & reservations if you feel otherwise :)
