Still enjoying my OF experience but had a thought about calendar integration. In the old days, OF would link to calendar so that you would get notices. Nowadays it gives it own notices, which in the Apple ecosystem are fairly universal. But one little app I love is “In Your Face” which, as its name implies, really, REALLY gets your attention. So maybe an option would be to have an API for them (long shot) or bring back calendar notices (medium shot).
Just my .02 cents worth in this wonderful OF world we all live in!
