Go Map!! is now a desktop app for Mac, in the App Store: https://apps.apple.com/us/app/go-map/id592990211

Did anybody ask for a desktop version? In fact a few people did, but the primary reason to release it is “because we can.” Many people edit using iPad, and many of those people use mouse/keyboard, so adding support for those input methods got the app 80% of the way to full desktop support. Enjoy!
