Versi 1.3.0 menambahkan viewer gamerule per-dimension dengan pagination dan pengelolaan gamemode player berdasarkan dimension, sambil mempertahankan portal antar-dimensi, last-position, minimum playtime, dan konfigurasi terpusat di `config/lobby/`.

+Minecraft menyimpan gamemode pada player, bukan pada dimension. Lobby Systems v1.3.0 menambahkan mapping dimension → gamemode dan menerapkannya ketika player masuk ke dimension tersebut. File ini dibuat otomatis dan dapat dikelola lewat command admin.
+
+Contoh:
+
+```json
+{

+  "minecraft:worldcreative": "creative",
+  "minecraft:overworld": "survival"
+}
+```

+Gamemode yang didukung: `survival`, `creative`, `adventure`, dan `spectator`.

+### Gamerule viewer per dimension
+
+`/ls gamerule <dimension>` menampilkan gamerule aktual dari dimension yang sedang ter-load. Viewer ini bersifat read-only dan cocok dipakai bersama WorldGameRules. Hasil ditampilkan 10 rule per halaman.
+
+Contoh:
+
+```text
+/ls gamerule minecraft:lobby
+/ls gamerule minecraft:lobby --page 2
+```
+
+Header chat menampilkan `halaman/total halaman`, nama dimension, dan jumlah gamerule. Jika masih ada halaman berikutnya, command untuk membuka halaman selanjutnya ikut ditampilkan.
+
+### Gamemode per dimension
+
+Gunakan mapping gamemode agar player otomatis mendapat gamemode yang sesuai saat memasuki dimension. Contoh:
+
+```text
+/ls gamemode set minecraft:lobby adventure
+/ls gamemode set minecraft:worldcreative creative
+/ls gamemode set minecraft:overworld survival
+```
+
+`/ls gamemode <dimension>` melihat mapping satu dimension, `/ls gamemode list` melihat semua mapping, dan `/ls gamemode remove <dimension>` menghapus mapping. Mapping disimpan ke `config/lobby/dimension-gamemodes.json` dan ikut direload oleh `/ls reload`.
+
 ### `/ls reload`

 Reload live:

 - `config/lobby/config.json`
 - `config/lobby/portals.json`
+- `config/lobby/dimension-gamemodes.json`
 - lobby exclusion pada player-position store

 Tidak perlu restart untuk perubahan JSON tersebut.
