Thanks for keeping it on your radar.
I think I understand why the bug is there. The plug-in assumes that if I’m looking at an event in February, it must be February. So if I look back at January etc., I’ll get it in closest order to where I am – i.e., in reverse chronological order. That’s not such a big problem. The real problem is that having done that, if I then go to the “month” view for that prior chronologically backwards list, the calendar month shows up EMPTY of events altogether! Try it to see what I mean.
