If you ever wanted to free up space on your Toolbar by removing the Layout Selector, only to discover there is no other way to change the layout, you'll love this free little tool. Simply drop the DLL into the Act! Plugins folder (with Act! closed), and make sure it's unblocked (right-click, properties, and click "unblock" if needed). Start Act! again, and use Tools>Layout Switcher to access this feature.
Now you can free up the biggest space waster on your toolbar by deleting the layout selector, and allowing room for more Actcessories without causing the toolbar to spill into a second row.
