If you've updated to the CRM2013 Spring '14 Wave (Service Pack 1) I think you'll agree that it contains some pretty awesome features.
You can read a good roundup of the developer features in the SDK (http://msdn.microsoft.com/en-us/library/gg309589.aspx#BKMK_NewInSpring2014) but have you noticed that there is a little less white space across the top of your forms? This is because the Command Bar now shows 7 rather than 5 buttons before buttons are added to the ellipses overflow.
It is worth noting that the number of buttons that are displayed before the overflow is not (yet?) configurable and nor can you revert back to displaying only 5 (pre SP1). That said, I really appreciate this little change that is a result of the product team listening to feedback from users. What's more it has no impact on the Ribbon Xml or Ribbon Workbench.
You might like to read more about the Command Bar in my post from way back when CRM2013 was first released.
