Tab Launcher provides neat and easy access to your apps and lets you basically have a second dock on your Mac. Tab Launcher can be divided into tabs where you can categorize your apps by type. You can also add, edit, and delete tabs, and add / remove as many apps as you like. Simply drag an App from Finder and plonk it onto one of the tabs to create a shortcut.
You can choose between various display preferences that let you pick between having Tab Launcher visible or hidden. When you move your mouse over Tab Launcher it expands and presents your apps, click on an app and it launches.
Tab Launcher is free for a limited time and can be picked up from the Mac App Store.
