Maple is a powerful tree outline manager software that allows power users to create hierarchical trees to store and organize documents, notes, and images. The software supports unlimited nodes and sub-nodes and the ability to assign any document to a node.

Adding a new node to your tree is as simple as selecting Add Node from the Tree menu, creating a new 'branch' which you can later name or rename. There's no limit to how many nodes or sub-nodes you can create, and you can easily assign any document or image to each node. If you need to delete all child nodes of a selected node, simply click the Delete Children button.
With Maple's Collapse All or Expand All options, you can quickly expand or collapse your tree as needed. Maple supports a wide range of file types, including OPML, standard text files, Rich Text Format, Word doc and docx, Windows Write, Adobe PDF, and HTML files used by Microsoft Word and other word processors.
One great feature of Maple is the level of control you have over text and tree appearance. You can use any font installed on your system, control the font size and attributes, increase or decrease text size onscreen, and change the text alignment (flush left, centered, or flush right). You can quickly create numbered or bulleted lists, headers, footers, and tables, and even create custom styles for your text that define a font, face, attributes, color, alignment, etc.
In addition to these features, Maple also comes with a built-in spell checker, password generator, and the ability to embed or link to images or files. You can change the case of text to all upper or lower, and use the character map and font preview in the font selection window to quickly assess what fonts look like. There's also a print preview feature.
Overall, Maple is a versatile and powerful software that's perfect for power users looking to create and manage hierarchical trees of information in an intuitive way.
