This would just be fantabulisticly amazing. I am picturing numerous possibilities with this soon to be released api.
Somethings that are a must is the ability to create a login / registration system, allow user interactions that sends data to our databases (eg. favourite, saving, searching something... etc.), custom code that could grab data from our databases (if you guys are using node.js as your backend ... we could insert plain js in our custom code to grab data and do something with it to display to our users) ... and so much more.
Webflow future is so bright ... you guys could become more than a web app tool for web designers and prototype tool for developers but a eCommerce / larger enterprise / web app creator + manager + cms + host and just being in our everyday lives. The current cms .. even though game changing and quite powerful ... it limits a lot due to the fact that you guys have to be our host with no ability to access / manipulate data and no exporting is possible ... thus is why I haven't dare touch the cms ... no matter how much I want to.
I hope to test out Webflow limits soon and wish that this api could come out asap!
