How to hide the Visual Designer from other CMS users
In preview mode, all content editors can access the Visual Designer for the uSkinned Site Builder. There will be times when this is useful but for some content editors you would rather they did not have access to this. Don't worry, hiding this couldn't be easier.
Login to the CMS.
In the tree menu on the left-hand side, go to 'Designs'.
In the top-right, click on 'Content'.
At the label 'Hide design panel', set the switch to 'Yes'.
Now hit 'Save and publish'. The next time you view preview mode the 'Visual Designer' will no longer be available.
