This addon provides the ability to prevent accidentally closing a tab via the "X" for tabs in Tree Style Tab that you consider important and don't want to lose. Holding "Ctrl + Shift" while clicking on a tab will replace the "X" with a lock graphic. Doing this action again will remove the lock and restore the default behavior. You can still close the tab (even with the lock displayed) by right-clicking on the tab and selecting the menu item "Close Tab".
