This type of thing is my biggest complaint with OSX.

I've been using OSX as my main desktop OS for about a year now, and it's unbelievable how many simple customizations require third party products. To make it worse, a lot of them cost money.

Coming from Debian and Fluxbox I'm used to almost any possible configuration or customization being possible via /etc, the files in ~/.fluxbox/, or utilities installed using synaptic.

Thanks for the tip! I didn't know about RightZoom.

Here are some little known Mac utilities I like:

* MutableCode's Breakaway let's you configure separate audio volumes (including silence) for with and without headphones.

* Stereopsis' Flux adjusts your display's color temperature to match the type of lighting in your room (e.g. daylight, halogen, fluorescent) to avoid the blindly blue glare in a dark room.

F.lux is actually available for all platforms! I've been using it on Windows for a while, one of my favorite small utilities.

Well, not iOS yet.

Separate volume bars for speakers/headphones are already maintained, no?

They certainly are on my work Mac (Snow Leopard).
