Thanks, that’s helpful. Those are the two things I use the most, too. One development tool I use frequently is the util.ac function (for “auto-complete”) that takes a glob pattern and returns all the globals whose names match. I didn’t want to make people have to define or update their Goal lib path, so in recent versions of ari I’ve been packaging all of the Goal libs and ari's into a libs FS that you can use with import.
