After submitting a form the form redirects to the success message which is always "Form submitted successfully."
Although it's possible to route to another publicly available site instead, it would be awesome to just modify the text message to reflect different languages. In our case it would be sufficient to have that text in German without the need to build a whole site for this and host it.

Similar to booking sites. Having the ability to have 2 date controls with the second date control not having the ability to select a date before the first date control. Or at least to fail validation is date2 is earlier than Date1

When placing fields and I have 4 controls, but I may need to change some out but can't due to only having 4. EG>>

City, Country, State, Zip Code
If country equals Australia I want the drop down with Australian states
If the country equals USA I want a drop down that only has USA states, But I can't because I can't design the form to include all the different State fields I require for my rules.

I have the need to enter currency type fields that have the appropriate mask format for the country.

Create a new data type for Currency, in Nintex Forms so that so that data can be entered in the form “19.590,00”,“2.000.000,00”, “25.560,00”, “900,00”

Header fields should be choices for the "When " condition on the Rule builder, to allow for easier conditionals.

Example:
When [header field] Visible (yes)
Then [another question or header field] Visible (no)

In the nintex sharepoint forms, you can specify how many columns you would like your choices to be laid out in. This makes it easy to configure your form so it is easily readable. In the NWC form, it is only possible to have your choices in a single column (sometimes this can be super lonh) or running together. in a row (hard to scan). It would be helpful to be able to have additional formatting options, like multi-column

Right now the validation error message of the e-mail control in NWC is "The email is not valid."
It would be helpful to add custom messages so that we can translate this message to different languages or additional information.

With the 'When form loads' rule builder, we should not expose the 'Form' 'Is loaded' selection in the UI. This is redundant based on the button that the user just selected.

We also should automatically expose the 'Browser Query Parameter' as that is really the information that the user needs, and without it being exposed, there's nothing in the UI that lets the user know it even exists.

Within the Start Event: Nintex configuration window (or any forms dialog), the fact that there are no variables should be called out initially. This helps imply that there can be variables associated with the form.
