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

Install this module via composer:

composer require i-lateral/silverstripe-modeladminplus
