Getting Started
Upon opening the app, you will be greeted by a list of your Minecraft worlds. If your world doesn't appear, try pressing "Show more" at the bottom of the list.
To begin editing, open the world you'll be making changes to by clicking on its tab in the list.

NOTE
If your world still doesn't show up after pressing "Show more", then that is a bug. File an issue here with details of your Minecraft configuration.
World View
Once you have opened a world, you will see a selection of tabs to the left, each pertaining to an aspect of the world you can edit. Here, the World Settings tab is selected.
Depending on the tab, you may have a selection of Node, Prismarine-NBT, SNBT, or another format of displaying the data. For most tabs, the Node editor format will be available.

Database Tab
Minecraft Bedrock uses LevelDB to store world data, a flat key-value database. Due to this flat nature, every single key-value pair can be sorted in one list. This is what the View Files tab displays.

Integrations Tab
As the Script API for Minecraft Bedrock is rather limiting, add-ons can struggle to implement advanced features. The Integrations tab allows add-ons to leverage Bedrock World Editor's capabilities, bypassing constraints of the Script API.
Currently, WorldEdit Bedrock by SIsilicon leverages Bedrock World Editor for its biome modification and structure import export features. For more information, see the dedicated integration page here.
NOTE
Integrations are implemented on a case-by-case basis. If you would like to add an integration for your add-on, make a suggestion here.
