This is easily the best app search tool I have found. Admittedly  all it really does is take the Search Apps textbox and repackages it into a simple icon and adds some features  but that is very handy. It offers a simple user experience. It displays and searches through all the apps on your device. It can be set to launch apps automatically. And it closes automatically once you've opened an app (i.e. it doesn't continue to run in the background). There is no lag  and there are no ads. This is as close to using a folderless system for apps as you can get. And I almost forgot to mention  it's very FAST.
