Oh ... sheesh. That's good to hear! When you're running with an existing set of package files you can "watch" tcl library and xql files and reload them either through the APM by hand or let it do so automatically.
But the creation of new files ... hmmm ... you can find them and add them to your .info files but I don't think there's an option to source new tcl library or load new xql files. I'll look into this, it would be useful.
