It looks like the world editor for Minecraft Bedrock does exist after all

Many Minecraft fans may have already heard about the development of an official map editor for the game, but @RogerBadgerman provided substantial evidence of its existence on his Twitter account. The editor will allow users to edit the game's maps (logical, right?) as they wish or build huge structures many times faster.

Many will say that users have already made perhaps a hundred editors based on the classic Java version of the game, but the official editor will also be launched on Minecratf Bedrock, the loose multiplatform version of Minecraft that helped the game reach such heights.

The video from @RogerBadgerman demonstrates some of the intuitive, brush-like tools for creating blocks in the Minecraft world, and shows copying and pasting everything from single blocks to massive structures. The functionality shown by the insider is impressive, but so far, Mojang developers have not provided information on when the editor will be released.
