The content team is hard at work publishing new how-to guides for all Nintex products. There's a new video released with a walk through of using the Style Profile Designer to edit your colors used in SmartForms (https://community.nintex.com/t5/Nintex-K2-Five/Work-with-the-Style-Profile-Designer-Colors-Editor-Part-1/ta-p/227356). The team is also working on adding new videos and walk throughs for the features that have been recently released, in K2 Five (5.6) or coming soon to K2 Cloud in the late 2022 release.
One way to stay in the loop when new content is published is to go to the home page of the How-To Center for your product (K2 Five or K2 Cloud), and under the options menu, select Subscribe (or Subscribe to RSS Feed). This will notify you when new content is published. The team is also tagging content as beginner, intermediate, or advanced so you can explore content relevant to your K2 experience.
