These are client-side quality of life mods included in the modpack that help you manage and find your stored items more efficiently.
Chest Tracker helps you keep track of items stored across all your chests and containers. Instead of opening every chest to find what you're looking for, Chest Tracker remembers what's inside each one.
Chest Tracker makes organising your storage much easier, especially when you have large bases with many chests spread across different areas.
Shulker boxes are portable storage containers that keep their contents when broken, making them perfect for transporting items. You can obtain them by crafting (Shulker Shell + Chest) or purchasing from the server shop.
You can open a shulker box directly from your inventory by Shift + Right Clicking it — no need to place it down first.
ShulkerBoxTooltip lets you easily view the contents of a shulker box without having to place it down and open it.
This is particularly useful for keeping your inventory organised when carrying multiple shulker boxes, as you can quickly identify which one contains the items you need.
