User reviews

Google Calendar Quick Duplicate is praised for its simplicity, time-saving Alt+Click shortcut, and usefulness in duplicating events quickly. However, a frequent complaint is that after duplicating, the calendar view resets to the current date, disrupting workflow when planning future events. Other issues include inconsistent button appearance, occasional malfunctioning of the duplicate feature, and unexpected calendar navigation after duplication. Despite these drawbacks, users find the extension helpful and a valuable enhancement to Google Calendar functionality.

Cons

After duplicating, the calendar view often resets to the current date or week, which is annoying for planning future events.
Duplicate button appearance (color and alignment) is inconsistent with other buttons.
Issues with duplicating events that are scheduled far in advance (e.g., months ahead), causing navigation back to the current date.
Some users report the duplicate button or shortcut not appearing or working properly at times.
Duplicate action sometimes moves the view to the previous week or month, causing confusion.

Working great, the only thing that can be edited is to chose number of duplication like two or three duplication and the other thing is that it changes the view after duplication done to 7 days and changes the week start day

Unusable, clicking the duplicate button just brings you to current day without duplicating anything.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Google Calendar Quick Duplicate requires very minimum permissions.
