"Next question, then, is how do I submit that type of request?"
It appears as if Ancestry.com just recently revised this process, but here is how you do it
In FTM 2012 Plan View go to the small window pane on the right
Click on Links
Click on Family Tree Maker - This last step will take you to a Family Tree Maker Advertisement
At the top of the Advertisement click on "Technical Support"
This will take you to a new form
On the right side of that new form There is a header saying "Give Feedback"
Click on the underline portion "Please let us Know"
This will take you to a form that will let you provide them your suggestion
Note: Since that form is somewhat diffiult to deal with when entering your text for the suggestion I always create my suggestion in MS Word and then when I feel I have it say what I want it to say I copy and paste the suggestion into the form
PS- The above process [although cumbersome] wil allow you to send in your enhncement
