User reviews

GCalPlus is praised for improving Google Calendar usability by blocking unintentional month changes, adding visual event distinctions, and offering customization features. The developer's responsiveness is highly appreciated. However, users report intermittent bugs, features disappearing or breaking after updates, and occasional UI layout issues. Some functions require reinstallation or reauthorization to restore. Despite these drawbacks, the extension remains valued for enhancing calendar navigation and visibility.

Pros

Effectively removes or blocks accidental month changes caused by mouse scroll in Google Calendar, improving user experience.
Adds useful visual enhancements like colored backgrounds for events, making calendar organization clearer and more visually distinct.
Provides customization options such as limiting visible hours and decluttering calendar views.
Developer is responsive and actively maintains the extension, promptly addressing bugs and user concerns.
Includes helpful features like multiple event copying and options to highlight busy days on smaller calendar previews.

Cons

Extension occasionally becomes buggy after updates, causing issues like menus disappearing or the UI reloading unexpectedly.
Some features stop working sporadically, requiring users to uninstall, reinstall, or reauthorize multiple times without a guaranteed fix.
Certain options like 'Multiply copy' button and 'Alphabetical All Day Events' sometimes disappear or stop functioning.
The month view can have layout problems such as excessive white space, reducing usability and needing scrolling.
Users experience difficulty in continuing to see consistent functionality due to Google Calendar UI changes interfering with the extension's features.

Recent reviews

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. Chrome Version 135.0.7049.85 (Official Build) (64-bit)

Loved it! But after the latest update in March 25, it's buggy and keeps reloading, so I can't use google calendar properly anymore. I had to deactivate the extension! :( Hope it will work again eventually. Edit: Reinstalling worked! All good again, thank you! And the new feature (hovering over event shows description) is great!
