As someone who has been insanely grumpy about prototyping tools for too long, I must say, it's so well executed. This is what I expect from software, I'm impressed, they delivered!

Yup. Same experience. Kind of makes it useless to me.

The frame rate of my uploaded or mirrored animations sure are laggy. I can't really show that to stakeholders.

I had high hopes for the DSM as well, and though I haven't tried it yet, it's disappointing that there are some table stake features missing. In general, we're a little frustrated with our Sketch + InVision workflow and have been playing with Figma as an alternative (component library + style guide as well). Would be great if Figma capitalized on this and built some fancier handoff tools. Overall though, we love Figma.

I find my workflow is split between Illustrator and Sketch (with me avoiding Sketch's pen tool entirely). I still find the versatility of Illustrator's tools the best, so it's sort of odd (at least for me) when these tools attempt to encapsulate my workflow in their product to some degree. Let me easily import and edit vector images from other software and you'll have me onboard.
