SilverStripe ModelAdminPlus

Expanded version of ModelAdmin that adds some extra features:

Submitting SearchForm via a POST (meaning that complex fields that require an Ajax callback should now function).
Saving search results to a session rather than using the query string.
Adding bulk editing (using colymba/gridfield-bulk-editing-tools by default).
When generating export fields for a DataObject also checks if the object has export_fields
Automatically find and format DBDate/DBDatetime fields to DBDate.Nice
Automatic "default" filtering of objects based on a config variable or custom method in your search context
