Limited tools when importing a Minecraft world in Editor

Whenever I create a project within Editor, I get access to all of its features and tools. However, when I import a world from my Minecraft worlds, I only get access to a measly 6 tools and some other features. This is an annoying limitation that greatly reduces the usefulness of Editor as an app. If I can't edit my worlds in Editor like I can a brand new project, then the entire value in an app like Editor goes down tremendously. It's not even possible to convert Minecraft worlds into projects, which is absurd. Other than that, it is a great product, but would be much better with this functionality.
