Add a table/details overview (in addition to the grid)
Iit would be good to have a list/table view with album names down the left, and columns for other aspects like artist names, compliancy of different rules and maybe shortcuts to functionality, e.g. changing the art, file paths or tags within the overview screen.
The analogy are file explorers: typically they allow grid/thumbnail views as well as detail views where files can be ordered by different columns, and different metadata about the files can be viewed in the column cells.
Just as with the grid view, you would be able to filter by compliance or startsWith. The option would likely be just another entry on the bar after 'album count'.
