SmartLauncher tries to be the lightest launcher possible. However, in doing so it abandoned almost everything needed in a launcher: speed.
SmartLauncher has only ONE screen, and NO icons of shortcuts AT ALL. It also distorted wallpaper by squishing them into the single screen.
You have three buttons along the bottom: phone (brings up the default "dialer" app), drawer (brings up its version of the app drawer), and the right unlabelled button actually brings up the web browser.
The drawer actually brings up the apps in a LIST (one app per row), with a search box on top, instead of multiple icons per row. The drawer appears to do NO caching, so every thing you hit the drawer it rebuilds the list, and this leads to a HUGE delay of several seconds, completely negating the "simplicity".
Sorry, but this is a piece of junk.
