The first thing you have to do when you launch myAppLauncher is to configure the keyboard shortcut that will show the application. Each time that you press the chosen key, the application launcher will appear. When you stop using it, it won't close, it will just hide till you use the keyboard shortcut once again.
MyAppLauncher has a box where you have to write the application that you wan to launch. As you write it will show a list with the programs that match the search. When you find the application you just have to click on it and it will be launched.
This simplicity make myAppLauncher work very lightly and it hardly uses any system resources.
Try myAppLauncher and make searching for and launching your programs a lot more dynamic.
