Yes, I occasionally find the Application version useful.  Like when I want to
trace an application from the beginning & don't have a handy way to trap on
a tool call that I know it makes right at the start.  (It's really hard to
hit Apple-Option-Ctrl-Esc at just the right moment.  Using the App version
of the debugger and LOADing the program is much easier.)

Happens to me too.  (Why?  To keep life interesting, I think.)
