# Features

## GUI

Manage everything about your island from a single menu — members, visitors, bans, toggles and live island info.

## Phases

Progress your island through a long chain of **phases** (Plains, Forest, Desert, Cave, Nether, End, Ancient City and many more — 20 ship by default). Each phase defines its own blocks, item drops, enchantment drops and mob spawns. Advancing far enough unlocks the next phase automatically.

## Roles & Members

Islands are shared. Each player on an island holds a role — **Owner**, **Moderator**, **Trusted** or **Visitor** — and members can be invited, promoted, demoted, kicked or banned. The number of members allowed is controlled per permission group via `custom-max-players`.

## Visiting & Open/Close

Islands can be opened to visitors with `/is open` (and closed again with `/is close`), and other players can drop in with `/is visit <player>`.

## Generators

Give players placeable **generators** that periodically produce a weighted pool of blocks (wood, redstone, prismarine, amethyst, nether, dripstone…). Fully configurable in `generators.yml` — see [generators.md](/products/ultimateoneblock/generators.md).

## World Border

Each island is bounded by a resizable world border. Staff can expand a player's border with `/oneblockborder add <player> <size>` up to the configured maximum.

## Holograms

Leaderboard and info holograms with support for multiple providers: **HolographicDisplays**, **DecentHolograms**, **FancyHolograms** and **CMI**.
