Block permissions

This module provides additional permissions for finer grained access validation in managing blocks.

The following permissions are added:

• An administer blocks per enabled theme.
  This enables granting a client access to managing the blocks without them beeing able to change the blocks on the admin theme.
• Permissions per provider of block plugins.
  This enables granting a user permission to add certain types of blocks but not system block plugins.

This module is for Drupal 8 and 9.

  Difference:
