The Fill panel allows you to set (multiple) backgrounds for your element. Currently we support fills in the following forms:
To add a new fill, click the + button.
By default, a solid fill is added. Clicking the cogwheel button brings up a popover with tabs to switch between fill types.
The gradient tab contains a track that indicates the color stops. To switch to another stop, select it from the track and change the color.
To create a new color stop, click anywhere in the track. To change the stop position, drag the handlers in either direction. To remove the stop, click the trash icon on the left.
