I have very recently purchased Nomad after coming to it from desktop software like Blender and I’m phenomenally impressed with it. I know from searching the forums that a desktop version was announced and intended to be released last year so I presume it’s still on the way.
As a stopgap in the meantime, would it be possible to simply enable the iOS versions to work on Apple Macs? It’s literally one checkbox on App Store Connect under the Pricing and Availability tab. This would let the iPad version run on Mac computers until a proper desktop version comes out and give flexibility to use it on tablet or at your desk without the developer needing to spend development energy on another version.
