hide tray icon in menu bar on OSX

My menu bar is getting really full with all those icons.
It would be really nice to hide the WhatPulse icon.

Not really possible, as that would leave it without an interaction point…it’s either the menu bar or the dock and the dock is usually way more crowed than the menu bar.

Both are equally bad on my Mac :s

One of my applications hides it (Growl does it as well) and gives you the config/interaction screen when you start it again.
