When we are mobile, it is often the case that we work with only a subset of the SharePoint lists that are available to us. Two methods may be employed to hide unused Lists and Subsites. The first method requires administrative privileges and is described in the following article: http://www.infragistics.com/community/blogs/anand_raja/archive/2012/04/03/how-to-disable-the-viewing-of-specific-lists-in-shareplus.aspx .
This online video describes an alternative method that can be used by any SharePlus user.
