The library is very good at managing spaces for you! It's easy enough to pick up for any developer who has experience with JavaScript frameworks like Angular or ReactJS; but it also allows non frontend devs (like myself) to build out great UX designs without much hassle because their skillset doesn't go beyond HTML/CSS & JS development. There are some features they could add which would really help us as an enterprise organization develop our own apps faster such as customizing layouts per space, adding templates using Bootstrap4 CSS files instead of embedding them in JSON format etc.. But so far I'm happy with where things stand. We have been able to create more efficient workflows within our engineering teams by creating user interfaces for new tools we need internally.
