On previous versions of Ubuntu I had a menu listing installed applications, sorted by categories.
I never could find anything similar in Unity. The dash never lists any application so I must find the application's executable file in the console and manually make a shortcut.
I never was able to display anything looking like this.
Is there something I missed ? Do I have to install a lens or something ? How do you access the famous "application-lens" ?
Press Super(windows key) + A to open the Application's Lens or click on 1. as shown here:
You will see three lists / categories:
Click on the second one (2.) and you will see a list with all your installed applications.
Filter them by clicking on Filter results (3.).
If you want something similar to the Applications menu from GNOME, you can type the following in a terminal:
sudo apt-get install classicmenu-indicator
It took me a while to find that, and I think it's better than the Unity Dash.
Hope that helps you!!!
