I would like to request an improvement in the Attachments (/pages/viewpageattachments.action?pageId=?) screen function that shows the Attachment list by Page.
 
1. Currently, we can only delete 20 files by selecting a maximum of 20, but we would like to request a function to select and delete all files at once.
ex) 20 selected     Download     Delete
 
 2. I would like to request an additional feature that displays the result of summing the size of all Attachment File.  (total size)
