Indicator reports aggregate groups of people for each question.
Below is a Period Indicator Report, a type of indicator report. The answer to each question is itself a link to the underlying members of the group that fulfills the question.

Limitations
Right now reporting compatibility is used to bridge the gap between the old and new e.g. cohort builder, data exports. This reporting module has a lot of the core features for evaluating parts of a report but doesn't have a good UI yet for designing a full report. Cohort builder is probably best for adhoc querying unless there's something in there that isn't supported then you'd have to use the cohort query editor in the reporting module. Data exports can only be designed/exported using reporting compatibility. There's a feature in this module that let's you define some simple dataset definitions like a SQL-based dataset but we ripped out a lot of the other ones we were working on. So this module and the reporting compatibility are complementary at the moment.
