[Affinity Designer iPad Color Palette Import?]

Just commenting to remind you guys that it’s December and we still don’t have this feature. 

[Does reverse on the gradient tool not work?]

I don’t know if this is a feature or a bug. But it appears that you can only rotate/reverse gradients that have been applied to the stroke, but gradients that have been applied to the fill. Can’t imagine why this is how it works.
