The ASCII Tree Generator plugin converts indented outlines in Obsidian into structured ASCII tree diagrams. It provides a simple syntax using `=` characters to define hierarchy levels and automatically formats the output with box-drawing characters for clarity. The plugin supports unlimited nesting, making it ideal for visualizing project structures, technical documentation, or mind maps. Users can generate trees within markdown code blocks and view them in both editing and preview modes, ensuring a seamless workflow for organizing complex ideas in a structured, text-based format.
