We'd like to join everyone here, the reports section does look incomplete. What is good, it's a chance to make it the best reports section ever!
Especially, visitors analytics is something you cannot easily find elsewhere in admin, and yet it's invaluable information to run the shop !
For example, the Cart could enjoy simple but noticeable enhancements:
- added (Sub)Categories Viewed subsection,
- added more fields like visits time, source_ip to the Products/Cats viewed sections, and to banner statistics
- some kind of reset or a period selection to all report types,
- ability to sort it by any field(s).
It shouldn't be really fancy at all, rather it should be.. helpful. Afterall, any report only makes sense as much as its infos help admins to maintain their stores.
