Hi,
Not sure if anyone had shared this before. I found this neat plugin while searching for a easier way to add links to the front-end menu bar. Example, if you wanna add a sign up link or a forum hosted on a external domain to the menu bar, you could use this instead of hacking the theme. The best part is you don’t have to hack every other theme you change later on.
Check this out =>

Also check out this menu plugin which allow you to hide links which you doesn’t want to show in the menu bar.
