Hi Aternos Team, can you please add the following plugin?
Plugin name: Essentials
Plugin link: https://www.spigotmc.org/resources/bookshelf.71439/
It's an updated version of a plugin that's already listed on your database (from 2015). It gives users more usage of bookshelves, essentially making them containers for music disks, paper, and books! Really neat plugin.
Thank you! 
I appreciate this service. During the long crisis period with nothing to do, playing on my server is bringing me together with friends I haven't played with in months due to school.
