Hello, Aternos Team 
Would you please add mod "Timberjack" ?
link: https://minecraft.curseforge.com/projects/timberjack
Mod allows you to cut down trees more realistic, so no more annoying flying blocks of leaves and logs 
. It of course works on multiplayer and is optimized to not lag as much as you may think it could 
.
Thank You in advance 
!
