World Preview NH
by ABKQPO
World Preview NH lets players inspect a world's biomes on a full-screen map before the world is created, using the seed and settings already chosen on the Create World screen.
What it does
On the Create World screen, a 16×16 icon sits beside the World Type control and opens a preview of the biome layout. Clicking it opens an interactive biome map generated from the current seed and world settings, and a World Preview button on the world selection screen does the same for existing worlds. The map can be panned by dragging and zoomed between 1 and 2048 blocks per pixel with the scroll wheel.
The mod is a backport of World Preview for Minecraft 1.7.10, with the structure preview removed. Its files target Forge only, and the single game version covered is 1.7.10. The mod requires GTNH Lib, and it is client-side only, so servers do not need it. The code is released under the GNU Lesser General Public License v3.0 only and is open source, with public source code and an issue tracker.
Key features
Biome map preview
A full-screen, interactive biome map is generated from the seed before the world is created.
Heightmap and cave views
A colorized heightmap overlay can be toggled, and a cave mode shows cave biomes on the map.
Y-layer intersection
The map can display block layers at specific Y levels, so terrain can be read at a chosen height.

Specific X and Z coordinates can be jumped to, and a search filter highlights biomes by name.
Seed library
Up to 50 favorite seeds can be saved and loaded again from the library.

Use cases
Choosing a seed
A player can compare the biomes around a seed before committing to it, without creating and exploring the world first.
Checking existing worlds
The World Preview button lets players look at the biomes of worlds already saved in the selection list.
Who it’s for: Players on Minecraft 1.7.10 with Forge who want to check biomes and terrain before generating a world. The mod is only useful on the client, so it is not needed on a server.
