I add my kudos and encouragement to any consideration to add compatibility with Snow Leopard in the near future, even if only for some time. Some of us have perfectly sound machines and do not wish to (or cannot, for different reasons re hardware or workflow) upgrade to any of the newer OSs, including Yosemite, about to make its golden appearance (at least for now).... Especially when SL was the last of Steve Job's pups (or, well, kitty!) That said: Congrats on your launching success, Affinity Designer team! About time Adobe CS had some healthy—and powerful—competitor. Best of best wishes.
