Yea, I'm a fairly new Pixate user. I learned FramerJS fairly quickly and it's fantastic, albeit a significant learning curve for some. Floid is directly based on FrameJS and uses it as the framework, so you can do a lot of complex interactions. But I agree, the workflow and structure can be a bit cumbersome and clunky. But I find that the workflow for Pixate is a bit cumbersome as well. I still have to slice up and export each individual element and then organize those in new container layers in pixate. It's quite a lengthy and tedious process. Especially if your design changes even a little bit, you have to go through that export process again...exhausting.
I love, love, LOVE FramerJS' Sketch import handling. You can organize the groups and layers directly in sketch, and they'll be available in Framer (and updating is flawless...almost). Can't wait to see what Invision's Motion tool will be like. If Pixate can introduce a Sketch import feature, it would be soooo much better and easier to work with
