MS CRM 2013 has good look and feel but only the draw back is it is taking time to load a form because of Navigation bar and Command bars are taking time to load.
So, with SP1 release, Microsoft provided a feature of hiding Command bar and Navigation bar. We may get a scenarios like form doesn't require Command bar or Navigation bar. Only thing we need to do is pass below parameters on from URL as shown below.
navbar:
Controls whether the navigation bar is displayed and whether application navigation is available using the areas and subareas defined in the sitemap.
on:
The navigation bar is displayed. This is the default behavior if the navbar parameter is not used.
off :
The navigation bar is not displayed. People can navigate using other user interface elements or the back and forward buttons.
entity :
On an entity form, only the navigation options for related entities are available. After navigating to a related entity, a back button is displayed in the navigation bar to allow returning to the original record.
cmdbar:
Controls whether the command bar is displayed.
true :
The command bar is displayed. This is the default.
false :
The command bar is hidden.
Ex:
http://{Org Url}?etn=contact&navbar=off&cmdbar=false&pagetype=entitylistviewtype=1039
