Script Summary: Hides list tabs.
You can still navigate to the hidden lists via shortcuts (Ctrl+Shift+Left and Ctrl+Shift+Right) and other scripts.
To set which lists to hide choose "Change hidden tabs" in the "User script commands" menu. (This menu can be found in "Tools" > "Greasemonkey", or by rightclicking on the Greasemonkey icon in the status bar.)
