As a Figma user attempting to move to XD, the missing feature for me is the ease of creating storyboards of my designs, especially when designing animated web banners.
I don't understand why XD wants me to create a rectangle, then size it, then color it in order for my group to have a background. Then create a second rectangle so that the group can have a border over all elements in the group.
I was creating an artboard for each storyboard frame so that I could have content stay within the frame. But then XD doesn't group artboards or allow them to be stacked.
Researching shows I can mask with shapes, but then I have to mask each element in my storyboard frame?!
