No notifications. Mac Ventura, latest Chrome. That's the main reason I wanted this so it's not useful if that doesn't work. :-/

I really love your extension. The only problem is the light blue color on the left where it has the time. Is there any way to change that color to a dark blue or change the font color to black. Those of us who have eye issues, we cannot see the time. Thank you.

Used this for years but finally uninstalled to get rid of the new page opening. I read other reviews and the developer's responses but I still think opening a whole new page is intrusive. It was difficult to figure out which app did it and in the beginning I was getting this popup at least once a week. It's annoying. I don't need the features in Magnum, I actually tried it for a day and its way more than I want or need. If you gave users the ability opt out of these popups I would have kept the extension installed. You were right that some users weren't using it, I had not used it in months, and seeing this ad again made me make the decision to uninstall. It's great that the developers are working on something new that they are very proud of but this pushy style of advertisement is not the way to go, especially considering it never ends. Spacing it out isn't enough, if any other extension advertised their product this way they would be met with the same backlash. In many cases, this behavior from the extension or app would interpreted as a form of malware. I really hope the developers consider changing their advertising approach and find a way to show off their new project without being so disruptive. At the very least the ability to opt out would have satisfied many upset (former) users. If a user has the seen the ad three times and still didn't install it, it should be safe to assume they don't want it.

I used this for a few months, but for some reason it stopped working (12 June 2023), and I get an Error 400: unsupported_response_type when trying to authorize it. I'd go back to 5* in a second if the app works again

Worked great but once the ad on the quick view and the opening a tab unrequested started it's been a real nuisance. I thought Manganum was some sort of malware the first time it happened, and I'm still convinced it might be.

I LOVE this extension. I use it multiple times a day, everyday. However, I wish there was a way to remove the yellow advertisement for the "new version" of the manganum app. I've tried the manganum app. I don't like it. I don't want it. I like THIS extension. Honestly, I would even be will to pay a buck or two to make this advertisement and all future advertisements go away forever. EDIT: I see in previous comments that it is likely the "announcement" will be removed, but those comments are over a year old and the yellow box is still there.

Good idea but when I install it, it will only show 2 holidays and nothing else that I have on my calendar. I even created an event on the same day as the holiday it was showing. There are no real options in the settings to tell it what to display or how far to go out.

Finally found the source of the full page ad. Removed! Glad I did as it made me find an even better alternative.

The author engages in user-hostile behavior, opening a new tab as an ad to his other extension, without no indication that this extension did it. This is made exponentially worse by the fact that many users installed this extension after another extension with a very similar interface was discontinued and pointed users to install this one instead as a reasonable replacement. To the author: We don't care about your new extension. Arguably, your new extension is a misdirection on your part. Users that need more calendar features go to the official google calendar page. An extension is supposed to serve as a simple and quick lookup widget. Your new app reimplements the google calendar page. Nobody needs that.
