Optional Fields and User Update

I LOVE this plugin, and would definitely purchase the Pro version if it included the following features:

– include googleplus, twitter, facebook optional fields
– ability to not only create user records, but to post updates to existing user records (i.e. change roles, update user field values)
– ability to have an optional auth key stored within the plugin settings, to bypass the need for the nonce. I need to perform the post from a third party application (Infusionsoft), which does not support me retrieving the nonce value.

Would you be able to add these features to the Pro version??

Thanks!
