Up till now, hidden fields were visible in the my submissions grid, however the values stored in them could not be edited.
In this version we have made it possible to edit these values, just like any of the other form field.
This can come in handy if, for example, you've found out that your hidden field was filled with the wrong value from Salesforce. you could then just change the value and push it back to Salesforce.
We'd like to thank Tim Schug, for this request, which we believe is a great addition to our platform
Enjoy!
