I asked, I begged, I cried..

 ...and I finally got default formats.  

Now when you want a custom Format to be your default format, you can set it right from the Format button.

The new Format button looks like this when you click it:

<System Default Format> As it sounds.  This is the name of the format currently being displayed and is the system format.

Columns...  This is where you pick and choose your columns just as you did before.

Select pre-defined...  If you have saved formats in the past, you can load them from here.  Newly saved formats will also show here.

Save If you have a pre-defined report currently displayed and you make changes to it, this will save to the same format.

Save As... Select this to save to a new name an existing pre-defined report or the system default.

Assign as default... This is the really good stuff.  

A selected format can be set as your own personal default or the default for everyone.

This new feature is available EVERYWHERE the Format button is displayed, including from within a person's card (record). 

Also in today's release you can now check for duplicate email addresses. 

On the Search tool strip, you can find this in the File drop down menu.  It under Utilities->Find possible duplicates...

Note, this works ONLY on the primary email address column.
