Would be nice if colour palettes were stored as JSON which would make it easy to convert and import from other formats like .ase using tools like https://www.npmjs.com/package/ase-util.
Doing this would open up a bunch of cool possibilities like a palette creation/sharing site where you can easily grab the palette JSON and import it into Affinity. Just an idea stemming from frustration of me manually having to copy my swatch palettes from Fireworks into Affinity.
