That's been on the list since you mentioned it, and was pretty close to being in Alpha 5 but there wasn't enough time. It's now been buried under a bunch of other stuff, too
. I'll move it higher and keep your fingers crossed for seeing it next release... Hacking is a big part of Alpha 6, so I'll be trying to include as many of the hacking-related changes and features as possible (though I doubt I can get to them all, too many!).
