The only complaint I have with Affinity Design and Photo is that I would like to use products such as https://creativemarket.com/PinkCoffie/863256-AI-Gold-Foil-Kit-Essentials-Bonus%21or AP plugins, however, sadly, I do not find they are compatible with Affinity Design nor Affinity Photo.
Because the above isn't compatible, today I attempted to make my own foil style with the attached. Are there directions somewhere I am not finding that shows how to create styles? I tried Select All > create style, as well I tried Select All > Add Style From Selection. Neither worked.
