Customizing the email options

When sending an email, there is a “more” dropdown on the right side with a whole lot of options.  Is there a way to add one or more of those to the email toolbar?  I use the Insert Picture a lot and it would be nice to have it within easy reach.  If not that, can items on that list be moved up or down?

Please ignore!  I found it.  This program is so freaking cool!!  I now have the little “insert picture” icon on my Write new email page. 

Now, one more question.  Is it possible to add your own emots to the dropdown list?

Other than the customize option at the end of the More drop-down, there are no other options to personalize it.
