One of the things I’ve seen popping up on the Sugar forums lately is people looking for suggestions on hiding the left shortcut menu on their views. We do this in a number of places in the application, such as in Studio, Module Builder, in the AJAX Email client, and in step 3 of the Import module.
You can add this to output in the display() method of the view. To learn how to override views, check out the Sugar Developer Guide. Be sure to put your new view in the custom/ directory.
