Hi @aimee8586 ,May I know what is the use of adding loading status of
the page/component?If you would you like to track the time for each
component -Starting from version AEM 6.0, there is OOTB feature to
measure rendering time for each component on a page.It is accessible
through TouchUI, Developer mode.If you need them to have it rendered to
the end users - IMHO it is not good idea to expose your custom component
status to the end users. Regards,Santosh
