Pros
- Effectively stops mouse scroll from changing months, preventing accidental month jumps.
- Enhances Google Calendar by highlighting events with colored backgrounds, improving visibility.
- Allows customization like hiding non-active hours to declutter the calendar view.
- Supports useful features like multiple event copying and scheduling improvements that save time.
- Developer is responsive and quickly addresses bugs and user feedback.
Cons
- Extension occasionally glitches causing calendar views to misbehave, such as excessive white space or disappearing buttons.
- Recent updates have introduced bugs like continuous reloading and arrow key scrolling issues.
- Certain features like "Month's show busy dates" periodically stop working without a clear fix, requiring reinstallation or cache clearing.
- Some users experience issues with extension settings disappearing after authorization or the settings pop-out closing unexpectedly.
- Missing advanced features like multiple color labels for personal accounts and more precise time filters were noted.
Recent reviews
I have been using google calendar to run my business for nearly 2 decades. At some point 12-15 years ago, Calendar restricted the All Day Events section to just a tiny fraction of the screen, with no way to adjust. I just discovered this extension 15 minutes ago. Whoever wrote this app you are a god send! Thank you thank you thank you!

I searched and found this primarily for removing/blocking the mouse scroll changing the months in the calendar (so annoying and prone to making note/addition mistakes on events, etc).
It seemed to install without issues, but then when clicking the extension icon the page would quickly refresh and the 'settings' pop out would disappear. I read some previous reviews here mentioning the 'remove-reinstall' fix and removed the extension, closed the browser, opened it, navigated to the extension in the store, added it, opened Google calendar, and clicked on the icon, and then connect. After giving Google access permissions the extension icon now opens the settings pop out which remains open for selections to be made. Bueno!

I had the same problem as Sina Laura after the update. I tracked the issue down to this extension and then saw the developer's comment. I did the actions suggested and, bingo! It's working fine again. Thanks for the fix information.

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.
GCalPlus requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Chrome extension may turn malicious.
This is determined by the publisher and the Chrome extension reputation on
Chrome Web Store, the amount of time the Chrome extension has been
around, and other signals about the
Chrome extension. Our algorithms are not perfect, and are subject to change
as we discover new ways to detect malicious extensions. We recommend that you always
exercise caution when installing a Chrome extension.
GCalPlus has earned a good reputation and can be trusted.
