Google Calendar Grouping is a handy Chrome extension designed to enhance the user experience of Google Calendar. This tool allows users to create groups for multiple calendars, making it easy to switch between them instantly. Whether managing personal, work, or shared calendars, this extension simplifies the process, allowing for more efficient scheduling and organization.

One important feature to note is that Google Calendar only renders visible elements on the screen, meaning that calendars not currently displayed will not be selectable until they are rendered. This limitation ensures that users can maintain a clear view of their scheduling options while utilizing the grouping feature effectively.
