The ability to redirect a user after closing the form using the buttons on the ribbon (New Responsive Forms Designer).

[ ref:00D90q6Cb.5002v2WgeSf:ref ]

Like mentioned in this user voice: https://nintex.uservoice.com/forums/218293-4-nintex-forms-for-office-365/suggestions/19051840-improve-form-load-speed-in-o365, the loading speed for new responsive forms is not fast enough.
In the meantime, it would be good to display a loading icon or text like "Form loading, please wait" to not confuse users who want to use the form.

It would be good if you could either set the collapse functionality to collapsed by default and or apply a rule in the rules engine to collapse a group automatically.

Allow users to enter their custom submission successful page.

Currently the People Picker uses the SharePoint user profile service to access people information which may not be accessible for certain organisations.

It would be good to allow the People Picker to query agaainst the AzureAD to return people information.

Governments are using a more secure ways to sign electronically, and one of the most popular way is utilizing their PIV ID cards to sign documents. Digital Signature, which is a certificate and key pair allows the YOU to digitally sign a document or email, providing both integrity and non-repudiation.

More information of PIV digital signature can be read here:

In the Image Control the Image URL doesn't allow to use any Named Controls. It would be helpful if you can add Named Controls to the Image URL. This way if you grab a URL from another list you can add it to the Image Control.

Since CSS is not available in the New Responsive Forms we will like to have an option to hide the "Close" Nintex buttons showed in the header when the form is open as we have an option to hide the Print to PDF.

.nx-sp-form-runtime-header {
display: none;
}

We have a hyperlink added to a SharePoint page, when clicked, it will open new Nintex form of a document library. We need to prepopulate dropdown value on this Nintex form through passing field value in URL. GetQuerystring functionality works for On prem but, it is not available in Office365.

We can help end users to click on specific hyperlinks to prefill some fields in the new form.

Official support for Microsoft Teams by Nintex Forms for Office 365. Currently links in Teams to SharePoint lists with Nintex Forms do not display the Forms - just a blank page. I opened a ticket with Nintex support and was directed here to suggest official support because currently Microsoft Teams are not officially supported by Nintex Forms for Office 365.

I don't know if this is possible, but it would be good if you could have a button on the form that is available in view mode that would allow you to trigger workflows/actions. For multi-stage workflows with manual triggers, it can be a pain for end users to manually start a workflow, especially if they aren't too tech savvy.

Currently, the Managed Metadata Control performs very slowly when a term set has a large number of terms. Please improve control performance by only loading a portion of the terms similar to how the out of the box managed metadata control works in the SharePoint Online modern UI.

Need a connector for MS Graph API in Nintex forms for o365. This would open the ability to make calls to MS Graph for validation and creation of objects in Azure. This ability is available in PowerApps and would prefer to stick with Nintex.

Per a support ticket, I've been told "We do not support accessibility ( WCAG at any level or 508) currently. We are considering this, but we have no immediate plans or commitments to do this at this time."
We were told at the point of purchase that your product was accessible.
If you intend to work with higher education or government agencies, your tool should be fully accessible and meet WCAG 2.0 AA standards.

Two ways to show the description from the Term Store:
- when hovering over the term
- next to the term when adding in the managed metadata popup

This would greatly help users to pick the correct term.

The Nintex Form web part for SharePoint online has no configuration features. Ideally the form should be embedded on the page using the web part and just show the form. You shouldn't have to see the ribbon at the top of the screen or the grey area around the form. This way users can stay on the page and fill out a form without unnecessary scrolling or in page navigation due to pointless padding.

Unlike Sharepoint forms, you cannot click a button to view the entire underlying group assigned in the People Picker field.

In default SharePoint form when clicking on the tags to open the managed metadata picker you have the option to add new items if allowed. This functionality is missing in Nintex managed metadata control.

Labels are not correctly applied to form fields - primarily choice fields with responsive forms. For a non-sighted user they don't hear what the choices are for when trying to complete the form. This is a big accessibility issue that should be corrected.
