Useful, but mediocre

I remember when this app used to be much buggier, so there have indeed been some performance improvements over the last year or so. Still, this app feels largely ignored with no real upgrades to UX, and the while it certainly serves an important need, it does so with a mediocre experience. Navigating artboards is still annoying, and Sketch’s poor support for resolution variable designs means things look pixelated more often than I’d hope.
