A Git query language
This is pretty cool. Looks like it's local to the current repo which makes sense for most usage. Having something like this across a swathe of repos would be useful in different ways (ex: "<i>What has Bob committed over all the repos for our projects that involves the string 'billing'?</i>".<p>Minor off topic rant about the animated example: <i>Who doesn't put a space at the end of their prompt after the $?! Ugh!</i>
