TST Lock por Irv66

⚠ This addon extends and works only with Tree Style Tab.

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".
