Hi Mark,
In reports, would be nice an option to display the subtotal line at the top of its subgroup, instead of at the end of it. So the subtotal line could serve as a subgroup header instead of a subgroup footer. Because when the subtotal line is at the end we don't know to which subgroup the displayed investments belong until we scroll down the report (in the situation where the subtotal line is out of the screen).
So the request is actually to have a header displayed at the top of each subgroup, to see the group name first when reading (scrolling) normally from top to bottom. In fact, subtotal could remain in the subgroup footer, or moved in the header, or duplicated in both... could be some options.
PS : and would be nice if the separation between each group could be clearer, more visible. For example, more blank space between each subgroup and/or, for subgroup header/footer, different color and/or bigger size for font, and/or specific framing.
