SuperTab is a utility that comes as an alternative to using the Command+Tab key combination for accessing currently running apps on your Mac. This program also provides you with a quick way to launch utilities on your computer, access your favorite documents and folders, and check recent clippings directly from your desktop.
The app's main screen can be accessed by hitting the Command+Tab keys. Various sample Tab Rows will be displayed on your screen. You can customize the Tab Rows by adding or removing the elements you need. For example, you can create a Tab Row that contains your Dock items. The app is packed with several Tab Row sample profiles which can be displayed on your desktop if needed.
You can access additional program options by clicking the name of a Tab Row and selecting "SuperTab Settings" from the menu. From there, you can change the appearance of the Tab Rows (resize the rows, adjust opacity level, etc.), check the program's hotkeys, etc.
The only issue I have with this application is the fact that it occasionally takes a while to display the Tab Rows after hitting the Command+Tab keys.
Still, this program can definitely help you boost up your productivity as it offers you a very simple way to open apps, files, and folders. You should definitely give it a try if you want to work faster on your Mac.
