I'd like to see better security under the Manage -> Uploads screen.
Currently, I can set my users capabilities to prevent them from editing each others posts, but I can't prevent them from deleting each others uploads.
Any user who has the "upload files" capability gets access, via the "Manage -> Uploads" page, to all uploaded files, and can delete any of them.
I'd like to see a new capabilities added: "manage others uploads". Users without this capability would only see their own uploaded files on the page, whereas those *with* the "manage others uploads" capability would be able to see and delete *all* uploaded files.
I also agree with previously posted ideas that upload titles and descriptions should be searchable.
