NBTBrowser

A quick note

Be careful when modifying NBT files using this application. When editing tags, this editor parses from a serialized representation of NBT data before applying changes to the loaded NBT object. Nothing is saved until you run save. Be sure you know what you are doing before saving a file using this editor! For more information on stringified NBT, view some examples here.
