Component designer
Pyzed Design has a second mode for building components instead of windows: you draw the component like a
form, declare its properties and events in a panel, write the logic of its methods, and place it in forms or
inside other components, like scenes in Godot. A designed component is a pz.Component.

The full guide is in the Pyzed Design manual: Component designer.
