I would love a report that I could filter by program start and end date and see what programs occurred during that time, what category they were in, which ones ran, which ones were cancelled (requires a cancelled and reason option when making a class inactive). We do a lot of seasonal reporting and program volume/offered and dig deeper on what ran and what was cancelled due to no signups or other reasons.

Right now this takes downloading the entire activity tree and a lot of filtering and counting to figure out.
