Old Mac OS X versions (until Mountain Lion) don't provide you with the ability to move or hide the Menu Bar icons of third-party applications. You have to install third-party programs that were specialized into completing the aforementioned tasks. One example comes from the Bartender utility.
This application lives on your Menu Bar and features simple to configure settings. You will find various options in its Preferences menu which help you customize the appearance of your Menu Bar, define global hotkeys for immediately showing all of your status bar items, etc.
You can easily hide or move Apple's default app icons (Notification Center, Spotlight, Eject, Volume, etc.) as well as the icons of your third-party tools.
However, you won't need to download and install this program if you're using OS X versions later than Mountain Lion. Simply hold the Command key and rearrange your Menu Bar icons by clicking and dragging them to their new location. To remove icons, hold the Command key and drag them over your desktop area.
In conclusion, it's worth buying this program only if you're using a Mac that has Mountain Lion or other previous OS X versions installed.
