The Sketch Palettes plugin for saving and loading presets into the color picker has gotten a lot of use since I initially shared it here. There have been a bunch of feature requests and improvements since then, and one of the most common feature requests was to support gradients. Well, it now does!
With the help of Alan Dickinson, who reached out on GitHub, support for both gradients and pattern fills was added, as well as a dialog for selecting which fill types to include. We hope you'll find the new functionality useful!
