Some Mac OS X Menu Bar add ons
#Rating Bar puts a small iTunes star rating widget in your menu bar, making it easy to rate your music. I currently use the keyboard commands in Synergy to do this same thing and more(displays album artwork at the beginning of a new song, and provides play etc controls). It got me to thinking that it might be useful to list the ones that I use here for other folks to check out.
So those are the first two from left to right. The third one is BluePhoneMenu. It adds a menu with Signal and Battery strength for your Bluetooth enabled and supported phone (I have the Sony Ericcson T61x.) It also does on screen call notification, which is quite handy if you are a headphone wearing fool like myself.
Fourth from the left is the ubiquitous Quicksilver. I'll save everyone yet another description of this invaluable utility. Next to it is SlimBatteryMonitor which saves me some screen real estate on the menu bar for more utilities without taking away the functionality of the Apple battery monitor.
Next to that is the excellent, donationware, Menu Calendar. It gives me the current date without any hassles, access to a monthly calendar, and easy access to iCal. The rest are all Apple provided ones, Airport, Displays, Applescript, Security, Bluetooth, and Sound.
Got any that you can't live without that I missed? That's what the comments are for baby!!
