Yes, you're right.  It should use "info threads" and not some
abbreviated form. I don't know why it ever did use an abbreviated form.
That never should have happened.

Unfortunately, Insight was originally developed as an embedded debugger,
and very little has been done with it to really make it work WELL with
native targets. There is a lot of polishing to be done.

Doh! Silly me. Right now, I am uncertain if there is an "easy" way to
add things to menus. We would probably need to add something like gdb's
initialize.c hack to do this. I would suggest just adding the necessary
menus and like to the toolbar directly. If you add a keyboard shortcut
for accessing any new windows, be sure to include those in
srctextwin.itb, too.

The toolbar stuff (and the menus, too) are all entangled inside
gdb/gdbtk/libary/srcbar.tcl and toolbar.tcl. Just follow what is done,
for example, with the function browser or some other window.

I think that's about it, but I may not remember everything. If you run
into any more problems, you know where to find me/us!
