To use a macro component, now we have to specify <?component name="..." macroURI=".../my.zul" ...?> in the zul page or define the macro component in lang-addon.xml. It will be convenient if developer can simply copy the macro zul file to a default or designated folder and the zul file is automatically registered as a macro component with the file name as the component tag name so developer can use it easily.
