XMenu allows you to add custom drop down menus
XMenu is a neat utility that put allows you to put up to six addition menu items in the menu bar.
Six Menu Possibilities with xMenu
There is the type of menus that you can add, each category has their own unique menu icon.
This menu item displays all the applications that you have in your Application Folder. This is an alternative approach to using the LaunchPad.
The downside is that if you have a lot of applications, it can take a while to find it. There's no searching and the applications are displayed by there name.
This menu item displays all the applications that you have in the Xcode Applications folder.
If your not a hardcore developer, you get Accessibility Inspector, Application Loader, FileMerger, and Instruments.
Tip: Probably not very useful menu item if your not a Developer.
All your Home Folders at your fingertips!
This is a great way to access common folders you use every day. Files in your Dropbox, Photos, Music, and Desktop can be accessed very easily.
This is just you user Document folder, which is located at ~/Documents
Most files that you save are kept in the Documents folder.
Create your own set of application/files that you want in the menu bar. This a very cool feature since you can put anything you want and it will be displayed in the drop-down menu.
Personally I think this is the best feature of xMenu.
This is a great way to declutter your System Dock, simply put "rarely" used applications in here. You'll still have quick access via the menu bar instead of the System Dock. You can create folders of like items so they might be easier to find.
Access common text snippets from the menu bar. However, with tools like LaunchBar and Keyboard Maestro, this doesn't really seem very useful. There's no scripting capability - you only display raw text.
This is neat to have feature, but for better productivity use Keyboard Maestro or TextExpander.
