I don’t think so because the notifications in chrome get buried for me. Email alerts for lost in the deluge of work emails. The Apple Watch helps a lot actually
I'm building a similar calendar notification tool for personal use on Windows so I understand the value of this. Calendar notifications via email and "reminders" on the iPhone are not effective for my workflow and I need something that's always active on my menu bar.
If this is all you need, why not just use an open source alternative? I'm using MeetingBar (https://github.com/leits/MeetingBar) and it covers all of these "issues". It even sends notifications, it's lightweight, scriptable and doesn't cost me as much as a Photoshop subscription.
