How about a free developer app? The current web developer handoff is already outdated. Due to Windows support, feature development is nonesistant. There have been few big feature updates since 2017. For designers it's fast and great. For everyone who works for designers, not so much.
Thanks for your feedback. We’re constantly working on the web developer handoff surface, and it’s had some significant updates in the past couple of years. What do you specifically think you’re missing?
By the way, we do have a large number of Windows users, so we do not intend to stop development on that platform.
