Die and everything goes into a grave, items in their own slots and all your XP. The mob that killed you stays to guard it: beat it yourself to get it all back. Grave compass, void- and lava-proof. Server-side.
Sleeping bags that never move your spawn and roll back into your pack in the morning, hammocks for a nap until dusk, and cushions at any pixel height with sneak + right-click. 16 colors each.
Satisfying buttons for every menu: they rise and glow on hover with a soft tick, sink when clicked, and sliders click in rising notes as you drag. Works on other mods' screens too. Client-side, nothing to configure.
A bestiary for every mob you meet: each one becomes a sticker in your album - faded until you find it, a page for every server, gold stickers for rare sights. Client-side.
Hold a treasure or explorer map to see how far its target is and which way to go, with a big arrow - and "Dig here!" when you stand on the X. The position comes from the map itself. Client-side.
Cinematic boss titles: when any boss appears, black bars slide in and its name comes up in big letters - and a victory card plays when you win. Works with modded and server bosses. Client-side.
Hover any armour, tool or weapon and the tooltip tells you how it compares to the one you are already using, as a plain difference. Client-side, works on any server.
