Ok, so a scriptlet it is.  I've never seen any other app that allows  
you to shrink further than the menubar, for apps that are the menubar  
type (i.e. not emacs.  The GNOME apps generally don't.

Its a good idea and something that should definitely happen. That's  
why its part of the PDDP templates (http://puredata.info/dev/pddp) but  
unfortunately not widely implemented.  How about following that spec,  
its close, but a bit simpler and designed to be easily parsed in Pd:

* the subpatch is called [pd META], and is not GOP
* each comment is a whole chunk of data
* the first word/atom is the datatype (i.e. no : at the end of it),  
case insensitive (removing a : in Pd is a little annoying)
* tags are space-separated not comma-separated (handling commas is a  
pain in Pd)

Strange it works for me on Ubuntu and Mac OS X. Where is it looking?
