Using the Nav Bar in Microsoft Dynamics CRM 2013 in an environment with a high number of entities can be challenging due to the sideways scrolling required to reach the other end. Keeping the mouse pointer steady to stop the Nav Bar from disappearing unintentionally requires a steady hand.
When not using a touch screen device, the traditional dropdown menu structure may be a more convenient method to navigate within the application. This free solution from +Scott Durow
brings a global Start Menu button into the #CRM2013
Command Bar that you can use to navigate from any part of the application to another menu or entity available in the sitemap. http://develop1.net/public/post/CRM-2013-e28098Start-Menue28099.aspx
