Thanks @butlerj for looking into it and creating the user voice. I like the description that you provided. You got my 3 votes.. I feel NWC forms still have long ways to go to catch up with the features in O365 and on prem.. Hopefully Nintex development team is giving some more love and attention to the cloud forms/workflows..
@cmikhaiel_e yeah now that object support is completed and released into NWC I know there are quite a few updates coming to NWC forms here in the next couple months:
Draft forms (save and continue)
Submission tracking post submission
Repeating sections
Improvements to data sources (hopefully this request will be included)
Definitely keep your eyes on the Beamer feed within NWC here in the near future.
