Day-O para Mac

I've loved Day-O for years, it's great! I just installed Day-O 3 (from April 2020, "finally updated for macOS 10.15 Catalina") on a new MacBook with Apple Silicon chip running 12.3.1 Monterey. It runs fine, but the Preferences window won't come up. Anyone know if there's a 'secret' resource file i can just edit for my prefs (or copy from my other Mac)? I don't need to change them often.

Day 0 can't be opened because Apple cannot check it for malicious software... Software needs to be updated?

Nice tight simple Calendar that connects with Apple Calendar events and lets me see a month at a glance. Thank you Shaun for Day-O. I also have ItsyCal but Day-O is ultimately more useful because of Events. Why doesn't Apple integrate their own software like this. Notifications, Menubar Time Date and Calendar should all just smoothly interact. They don't.

It's what the built-in date/time menu bar widget should be.
