In the AdminCP we can search for attachments based on filename and many other qualities. However, we cannot easily find the attachment if we only have a URL that is direct link to the attachment.
I wish I could easily find the attachment in the AdminCP by just entering the attachmentid. Now I have to figure out the file name, search for that, and sort through all the results that may have similar file names in order to find the attachment referenced in the URL I was sent.
