Create a GOV focused accessibility compliant theme
Essentially make a theme that looks and feel like GOV.UK, UK Gov Style. This would be a big tick if Nintex are looking at targeting other government departments within the UK. Other regions in EMEA and Worldwide I am sure would be interested.
The feedback from Government customers on smartforms today is that they are still getting challenged on accessibility requirements.
Watch for the coming feature to add custom CSS into Style Profiles, releasing later this year for both K2 Five and K2 Cloud. You will be able to link external CSS files into your Style Profile to use in SmartForms, which should unlock this capability. Try it out when it releases and let us know your feedback. Thanks!
