One of the lesser known features of CRM 2011 was the File->Properties dialog that you could view on a record form. It would look something like:
This dialog was very useful for finding out the effective permissions of the current user on a particular record but in CRM 2013 it is no longer present in the user interface – but it is still there in the background!
If you used to use this dialog in CRM 2011 I've created a managed solution that provides you with a Properties button on the Command Bar that shows the CRM 2013 version of this dialog.
FormPropertiesButton_1_0_0_0_managed.zip (2.39 kb)

After installing the solution, you should see a new button in the Command Bar overflow menu:
The dialog looks like this:
The only down side is clicking OK gives the 'Are you sure you want to navigate away from this page' dialog.
Hope this helps.
