Thanks for asking 
We’re all focused on shipping PG 3 as soon as possible. That said, compared to v1 and v2, for v3 we’re not making any compromises in terms of UI usability and core features like new drag & drop, multi-select, full support for CSS/LESS/SASS, working with multiple device sizes etc.
In the process we re-developed large parts of the app.
Most features are in place now and we’re implementing the new UI and design. As soon as we have that in place we’ll share more details here.
