Awesome addition to fabledskyblock would be minions, something like Hypixel has on their skyblock.
I have been looking around for something like what they have and could not find anything quite like it.
Features would include:
Upgrades such as compactor, auto smelter, etc.
Auto selling upgrade
Fuel to increase speeds
Minion skins? Not that important, just cosmetic.
Upgrade minions for faster speeds & larger storage
Ability to work while players are offline
Most of these abilities should be done through custom items as well, like having an "Auto Smelter" upgrade which can be crafted and placed onto a minion and can be removed.
Minions can be used for trees, ores, crops, mobs.
Minions should be placeable, and ability to pick them up.
Limit the amount that can be placed on an island using fabledskyblock.
Permissions for more minions on island ^
