App
Kinda nice to see your report's data columns in alphabetical or numeric order, which you can do by clicking the column you'd like to sort.
But then, on the other hand, pretty annoying when you then subgroup your data, and those columns just don't care about the sorting you chose. They have previously lived their own life and mixed as they saw fit, but no mo'.
If you subgroup your data columns in reports and sort your table, the subgroups now also consider your sorting. Neato burrito!
