Ask HN: Which app or tool (no longer existing/discontinued) do you miss most?

Which app or tool (if any!) that is no longer developed or supported — or perhaps so far from mainstream that it’s practically dead — you used to use a lot, like a lot and now miss a lot? Can be pro or personal. Feel free to share more than one, if you like.

I remember that I was pretty sad when Macromedia (later Adobe) Fireworks stopped being developed. I always liked it better than Ps. But that was "a while" ago and right now we have far better tools, like Figma.

Does our industry leave any space for tech-nostalgia at all? Or is the current toolstack just better in every respect?

Thanks for any comment. :-)
