Stone Tools: Exploring retro productivity software from the 8/16-bit era. No games, just work. (https://stonetools.ghost.io/)
Spotted this on today's This Week in Retro (https://www.youtube.com/watch?v=UHYscl1Ayqg) podcast, which is generally very games-focused. The first article is up now, cataloguing a comprehensive history of Deluxe Paint, which, of course, was the raster art program prior to Photoshop achieving sentience; Doom, Quake, and Duke Nukem 3D all owe their art to Deluxe Paint (albeit on the PC rather than the Amiga as showcased here. From what I know the PC version of DPaint was basically an exclave of the Amiga user experience, including the hold-right-mouse-button-to-access-menu-bar shenanigans. Even on SunOS, there was a clone, Caldera Graffiti (https://www.flickr.com/photos/96579068@N05/54577297427/in/album-72177720312764810), which is blatantly still using Workbench-style borders and fonts from its Amiga ancestor TVPaint.)
Here's hoping the blog covers some Mac software that got NeXT ports in future posts—there's no shortage of such programs.
