Remove applications from Menu in Elementary OS Luna

I've been using Elementary OS Luna 0.2 for a few months now, and I love it. It's light and quite stable for a system that's in beta testing. Like in Gnome-shell and Unity, installed applications clutter the menu with gritty and unnecessary icons. How do you remove them?

Option 1: Alacarte

There are two ways to remove the icons. Using alacarte is the easiest, but might not work for some people. To remove an icon, you have to install a menu editor, alacarte:

sudo apt-get install alacarte

Run the command "alacarte" from a terminal or the app menu and the program will open up:

Next, uncheck all unnecessary entries you wish to remove from the menu. Log out, and back in to notice the changes. 

Option 2: Delete the shortcuts from their folders

The applications menu in Luna and Isis display most shortcuts inside three folders. Open up Files, and head to these locations to remove the unwanted shortcuts:

• /usr/share/applications (needs root privileges)
• /usr/local/share/applications (needs root privileges)
• ~/.local/share/applications

Delete the app shortcuts you don't want.  To gain root privilige, right click on Files' Plank icon, and 'run as administrator'. Alternatively, you can use this terminal command:
sudo pantheon-files
The changes should be immediately noticeable. If you have any issues removing the application icons form Elementary OS, drop a comment below.
