I have moved an existing WP site to unite gallery (paid).  It's working really well for new posts.  However older posts need to be updated by hand, which is a pain. 

 Two features would help:

1. Allow a unite gallery to act as the default gallery.  (e.g. shortcode "[gallery]").  This would also mean the standard UI to add galleries would add a default unite gallery, which is, I think, what many people would want.
2. The WP internal gallery will handle missing attachment ids by displaying all attachments on a post.   E.g. shortcode  "[gallery]" works fine with the standard gallery, but unite requires "[gallery ids=....]".  Please emulate the built-in behavior.

Many thanks for a great plugin.  The mobile behavior is fantastic!

Hi, Thanks for the quick response!  

To clarify, the second request:  From inside a post, all uploaded media have post_parent set to the post.   The internal gallery, when invoked as "[gallery]", just shows these media.  On the other hand, unite gallery will give an error.

Here's the patch I'm using. to show what I mean. I'm not familiar with the wordpress api, so I just went with the most straightforward solution as I didn't see a quick way to get just the children ids.
