I have Windows 10. There is a program called Paint 3D. I opened it now and do not see guides or the option to turn on guides. I do not have an export option where I can preview different formats with different color palettes. If I had more time I could probably list other features Fireworks has that I have become accustomed to.

Oh and Fireworks is consistent. I can trust when I have a task I can open it and it will have expected behavior and features. The way modern software removes and add features and add and hides options on every update makes using the software a task in of itself, before doing the business at hand. I'd rather make my images and be on about my day.
