Hello, Aternos. How are you. 
Can you please add "Backpacks!" mod?
Yes, I know what you think "this mod is already in our store". But no, it is not, the one they have in their store is another VERY different one, although it is called same ... or almost the same. (Backpacks!≠Backpacks)

Description: Adds customizable backpacks that can be accessed from almost any GUI.
Thanks again! Bye bye!
