The idea of TabLauncher is not to replace the system's dock, but to help keep it clean, with only the applications that are currently running.
By removing all the application from the dock and organizing them on tabs, you can quickly find and run any application you want.
Apart from that, you can create as many tabs as you like, and personalize them by setting the background color, title color, and font. Just drag your favorite applications to your tabs and it's done! You can also rearrange the tabs by dragging them. And even rearrange the whole TabLauncher. Just drag it where ever you like along the sides or the bottom of the screen.
Now it takes less than 2 seconds to find and launch any app. (It's true, according to our statistics)
