+
+A button that allows you to create additional personally adjusted groups (beyond what is defined by default, such as "political map").
+
+The button appears after there is a new combination of layers, which does not yet have a representation in the dropdown of the predefined layers (Layers preset).
+
+In this mode, the combination text will default to "custom (unsaved)", until you click the plus button, which will prompt you to provide a predefined name.
