I totally agree that this is a much needed option for the OSX users.
...to further expland on this idea, I would also like a way to have a custom palette toggle that toggles a 'group' of palettes and toolbars or at the very least 'all' palettes and toolbars. I am constantly finding that I want to toggle most of my palletes except for my Tool palette, especially when working on my laptop.
Most of the time I don't need all of the palletes on screen but it's a pain to toggle palettes on/off as separate items plus I like keeping my WE as consistent as possible.
ArchiCAD could perhaps learn a trick or two from Adobe Illustrator. All of the toolbars toggle on and off by pressing the Tab-key. It is
nice, you can get a full-screen workspace at the click of a button.
