Version 1.5.0 is here, and adds a couple of new features! It is highly recommended to regenerate your config.yml for this update!

Changelog:

• XP on withdraw (config option + permission if more_permissions is enabled)
• Choose to give spawner to either hand or gui with /sc givespawner
• Open others' spawner/mob storage using /sc open
• With more_permissions enabled, you can now set per mob limit with permissions e.g. spawnercollectors.spawner.zombie.10
  
• Disable spawner ground placing to ensure no laggy mob farms are made
• Fixed givespawner command using the giver's permissions instead of the target's permissions
