Very intuitive and visually appealing plugin! Replaced building grades on my server with it and expose single removal of entities to my players. It uses the correct upgrade hooks to integrate with plugins like SkillTree. Just be careful of the REMOVE + ALL workflow, it can be tricky to notice and it has messed me up a few times.

I liked the plugin, user-friendly interface, customization, and pleasant to look at.
Clicking on icons to update a wall or delete it is much easier and simpler than writing a command manually in the chat, that’s why I like it. You can also remove, for example: stoves, workbench, box, and much more.
