Currently there are 4 items in statistics in the Action Window
Overview
Artist / Album
Albums
Ratings Breakdown
if you click to the top left, you get a pull down list with the same number of items.
How about an extra option in this pulldown, that could do sub totals, depending on the columns in the currently displayed view scheme.
So if you select a view scheme with 3 panes say, Genre, Album Artist (auto), Album, then go to statistics in the AW, you see an extra item Genre/Album Artist (auto)/Album (matches the panes in the viewscheme)
This would then display in the action window the subtotals of the above columns eg.
--------------------------------------------
Genre | AA (auto) | Album
--------------------------------------------
genre 1 | 5 | 10
genre 2 | 6 | 15
genre 1 has 5 AA(auto) which has 10 albums
genre 2 has 6 AA(auto) which has 15 albums
...and so on.
It would be helpful if the column headers (in AW) when clicked allow sorting like in PN. Now its possible to see largest & smallest depending on the column.
The idea is you could get subtotals depending on the columns set in whatever viewscheme is currently displayed.
