I wonder why not Axure? It is much closer to UX type of work, and Affinity Designer is more illustration-focused.
Hot-spotting some images isn’t really going to cut it.
I’m waiting for Framer X to come to windows (switched from Mac to Windows because Apple are taking the p*ss). But I think it’s going to be web only like Figma.
If that’s the case I might just use svelte for higher fidelity prototyping.
