Despite some good experiences, after quiet some working with Affinity I gave it up now. Why? Beause the color swatches in Affinity do not link to the objects. This is a major flaw that makes Affinity designer useless.
It means, you set a swatch color then set one or several object fillings using that swatch from the palette. When later changing the color of that swatch, the colors in the objects do not change accordingly. They are therefore not linked to the swatch.
Well, they then explained to me that there are so called "global colors" who can do that. But its like eveything so far in Affinitys applications, you need to consult a thick manual first, before you understand the unnecessary complicated behaviour.
And there are many many other things in AfD I really did not like. The complicated handling of color palettes and setting of color swatches. The incoherrent behaviour of tool settings, specifically brushes, who sometimes repeat settings, but mostly do not. The difficult handling of path points and path manipulations, which always need many more steps then I am used to from FH. Missing of basic tools like straight line, distortion etc. It´s a long list so I decided to stick to FreeHand in Parallels and wait if maybe some years from now Affinity may be getting there. I made my inputs in their forum, but from the responses it seems they are stuck with the complicated handling of things as they think more like engineers then like creative users.
