Only the Nucleo icons support by default all the customization options, including stroke editing and secondary colors. By unlocking the Nucleo icons, you can enjoy the full potential of the Nucleo app!
You can use the Icon Editor to extend the advanced customization options to all the icons you import into the Nucleo app.
