[Plugin: Formidable Forms] Period and div/fieldset features

Ciao,

what about adding three new field types:
1. period, i.e. [date-time](calendar)-[date-time](calendar), where (calendar) is the button to choose date and time;
2. fieldset/div, creates a fieldset or a div container where we can drag and drop other fields. We can set an id and one or more classes space separated.

Is it possible?
Does pro version already provide these features?
Thank you.
