#32 has a couple of open todos blocked by sonata and phpcr-odm missing features
the reordering is now done by https://github.com/sonata-project/SonataDoctrinePhpcrAdminBundle/blob/master/Form/Extension/CollectionTypeExtension.php
i updated the issue yesterday, added the checklist and removed it from the 1.0 milestone. its not critical at all but notes to clean up things once we did tasks in other bundles.
The auto naming is stll a todo here: https://github.com/symfony-cmf/BlockBundle/blob/master/Admin/Imagine/SlideshowBlockAdmin.php#L111
ok .. that sort of works as is .. so fine for me.
i created separate follow up tickets for the things that are still hacks. but definitely none of those blockers to release 1.0
