Interesting idea about being able to report on only recurring entries.
I’m wondering about the utility of such a report. I’m having difficulty thinking of a good use-case for it. For example, would I ever want to see just my recurring entries isolated from others? Not sure…
Or, are you suggesting that a report would show all data between a date range with start/end date range being either a) arbitrary or b) based on existing recurring event periods? The later could be challenging to understand – if I have an entry that repeat every week… will every week in the past/future be in a drop down?
I think I need more details to understand you properly.
