Based on what I see in Github, It appears that the standard field dropdown in the Salesforce Node is a static list of fields. The Contact object has the MobilePhone field present, however, the Lead object does not. Can this be added?

Just checked and you are right. Should be really easy to add. Added it to my todo list.
Got added. We will let you know when is released.
