Ubuntu: Surely you have installed an application and didn't know exactly where to find in in the menu so you had to go through all Gnome menus to find it. "Where is application (WIA)" is the solution to this problem. Every time you install an application, a message will pop-up telling you exactly where to find it in the menu.

You can download WIA .deb and source files from here (look at the bottom of the page for the latest version - you will find it under the name "wia" - obviously).
