Today I updated the Post Gallery Widget plugin. This round of improvements are
- The widget now has a dropdown with a post order option. The options are by date, by menu_order or random.
- There is a meta box on the post gallery edit post screen to set the menu order of each post.
- The menu order auto inserts itself as a unique order and shuffles other gallery posts down if necessary.
If you already have the post gallery installed, this update should appear in your list of updates within the next 12 hours.
