Is that really true? I had a feeling that macOS desktop developers are on the decline.
There are certainly a lot of Windows-only apps that are quite nice.
Further, as a person trying to develop a cross-platform, desktop-only GUI framework and applications, macOS is absolutely the worst offender on nearly everything. From only supporting an outdated OpenGL version to requiring that windows are managed on the main thread. Neither Windows nor Linux have either of these limitations.
Workflowy is what I use. It's cross platform, but a lot clunkier than this.
