I design software, and much of that work is done in Sketch. I’ve used it my whole career and will continue to do so as long as it stays a native app. Lucky for me, I think it will. (Kudos to whoever set that headline in ITC Garamond Narrow, and shame on whoever set the text in it.)
I was also worried that Origami Studio, another great tool I use, would go with Electron for their next big release, but I’m happy I was wrong!
