Vecte is a very simple app, designed as a replacment for the OS X application switcher.
Vecte is simply a replacement. All the standard keyboard shortcuts still work, the only difference is how it looks and feels. First of all, Vecte's window is up in the top-left corner of the screen, not in the way, in the middle of the screen. Second, Vecte switches apps instantly. It doesn't wait around until you let go of the Command key. Third, Vecte does not reorder the apps every time you switch to a new app. If you missed the app you were aiming for, it's still in the same spot. Just switch again!
