Don't. Something else might already be there.

For example there's a tool out there called "Hardcopy" which enables,
well, a hardcopy to clipboard, printer and whatnot by clicking on its
button located at exactly where the additional buttons sit in this

IIRC, TheBat! (email client) also has a special button sitting there,
which is not useable as long as hardcopy paints its button on top of it.
