Not sure if this is a duplicate of "Disable the images only to show" but the EG-Attachments plugin allows admins to choose not to show images in the list of attachments - presumably this is because images already appear in the body of a post and don't need repeating at the end.
This would be a great feature for Auto Attachments - it would mean that users wouldn't have to learn how to configure short-codes to filter the attachments. In fact, I just want the attachments to appear by magic whenever a user attaches things to a post - my users won't even know what a short-code is.
This is especially so for me as I want to put images in posts (and not have them appear as attachments) and I want to attach documents to meetings (and have them show up).
Thinking ahead, it would be good to be able to include / exclude certain post types from showing auto-attachments at all, as CollabPress (for example) already shows its own attachments in a project page/post, so it would be good to be able to switch off auto-attachments for this post type. In fact, it would be good to be able to select only those post types I need - namely calendar events.
Hope this is helpful.
