I like this app, but it is completely unusable when it causes the "CalendarAgent" to use a huge percent of your CPU. This happens on my M1 and Intel Mac. It does not happen with any other calendar app.
Wish I could give 4.5 stars as there is but one thing I wish it did. Otherwise it's just about perfect, for its intended purposes. That is, it is a very functional menubar version of Reminders. Having the dropdown window be larger is my one wish.
