Hi there,
I have attached a patch which adds a new capability to the=20
=E2=80=98ns-hide-emacs=E2=80=99 function in the NS port.  Specifically, it =
causes=20
the =E2=80=98ns-hide-emacs=E2=80=99 function to respond to being called wit=
h the=20
argument 'activate-front in a similar way to how it responds when=20
called with 'activate.  The difference is, instead of layering=20
every Emacs frame in front of every other application=E2=80=99s windows,=20
it only brings the selected frame forward.  I have uploaded a=20
small video of the new functionality in action here:=20
https://mfa.pw/activate-front.mp4

Please let me know if any modifications would need to be made to=20
this patch before it could be accepted.

Thanks for your time,
Matt
