Trampoline is the upgraded successor to Bullseye. If there are six or ten apps or folders that you use a lot, and you have a big screen, then eventually you will have spent weeks of your life just hauling the mouse over to the same few little spots in the dock. Trampoline makes a circular 'dock' appear right under your cursor, wherever it is, when you hit a chosen hotkey or Mighty Mouse button. It dismisses just as fast, so this thing doesn't get in your face much, but it can make your life a tiny bit smoother, many times a day. Folders can be nested, but otherwise this is not an app that tries to assimilate you with its mass of features. It's just a little launcher for your most used items.
