Dragging Things:
Adding Applications, Opening Files with applications on TabLauncher:
Adding Finder:

You can drag the Finder to any tab. It is located here: "/System/Library/CoreServices/Finder.app".
But maybe it's easier to drag the folders you use the most to a tab.
Resizing TabLauncher:
TabLauncher will increase it’s size to accommodate the biggest icons you have on all your tabs.
By shrinking the size of the icons on only one tab, the width will decrease but the hight will maintain.
If you shrink the icons on all tabs then the hight will also decrease.
Resizing the tabs:

Adjust the Appearance slider on the Tabs preferences menu.
Some styles include a smaller tab.
Radio
To add radio stations from http://www.shoutcast.com/ follow this steps:
1 - On shoutcast.com click Settings, then choose to play in default media player.

2 - Search for the radio you want and download the .pls file.
3 - Open the .pls file with TextEdit and copy the radio URL.

4 - Right click the music tab on TabLauncher, select "Add Radio" and paste the URL.

5 - Rename the newly created item, and it's ready to play.
We’re sorry, this is kind of tedious, we will add support for .pls files soon.
