Would absolutely love for Serif Labs to create a port for Affinity Photo and Designer. Of the programs I’ve tried, those two have the closest UX to Photoshop and Illustrator without the software-as-a-service model.
Hell, I’d even take it if all they did was support it working under WINE. While I would prefer a seamless UI that fits in with both GTK and Qt, it’s understandable that they might not consider it worth the effort.
