I have been using Webflow for a while and love it. Amazing product.
Something I think would be very cool would be a webflow app. The app would not be used for editing (obviously) but for testing and demonstrating. It would be very cool to have a webflow app that would provide easy access all of my sites. Just a simple site that provides a direct link the .io sites I have within the tool. I could have it installed on various devices for testing and it would be a great tool to show others the sites you are working on.
Just a thought,
Keep up the great work.
