Great presentation! Though the topics discussed are sometimes so hard to implement with a group.
Creating a consistent design language in UX-App (https://www.ux-app.com), a browser based mockup & prototyping tool, has been a real challenge for me because of the complexity of the options being offered.
But we’re making the brave decision of redesigning, specifically for the purpose of standardizing our design language and making the app consistently intuitive. This was a great lesson, and encouragement for our road ahead, so thank you!
