Given how Adobe's last purchase of a drawing program (buying Macromedia ten years after being told to wait a decade after buying Aldus and it being split off to be acquired by Macromedia and then off-shoring Freehand/MX to India and then burying it), good.
I still keep a copy of CS6 on my windows machine just for access to fireworks. I should probably learn something new at this point but there is just something about the presentation of the canvas, pixel snapping, and palettes that I can't give up.
I wouldn't be surprised if Adobe's decision to phase it out resulted in all these new UI design apps to appear in the market (Sketch, InVision, Figma, etc).
