Gwennel is a lightweight word processor that takes an innovative approach to formatting options by separating them into a tree-like structure. This is useful for handling long documents with clear, organized formatting tools or for users who wish to focus on the text first and formatting second. Any style changes (such as headings, lists, or colors) are propagated throughout the entire document and, although only able to open and save OpenDocument (.odt) files, this makes the program a capable WYSIWYG editor. Additionally, users can open existing files and make rapid changes to the entire document.
