The Creases plugin provides powerful tools to manage and fold markdown sections efficiently in Obsidian. It allows users to create 'creases' in their notes using fold markers (`%% fold %%`), making it easy to save and restore specific folding states. Users can fold headings by level, crease current folds, toggle creases, or iron them out entirely. The plugin supports workflows such as setting up folded content in templates and maintaining a 'save state' for folds during edits or searches. With additional support for the Templates and Templater plugins, Creases enhances organization and navigation in long documents.
