The Underline plugin adds functionality to easily apply underline formatting in Obsidian. By using the default hotkey, users can wrap selected text with `<u>` tags or insert an underline wrapper at the cursor position. The plugin also supports undoing underlines when applied text is reselected. Additional formatting options include wrapping text with `<center>` tags, headings, or block references, accessible through dedicated hotkeys. For even more customization, users are encouraged to explore integration with the Text Format plugin for custom wrappers.

The Cloze plugin for Obsidian enables you to create interactive clozes from highlighted, underlined, bolded texts, or any selected text in reading mode.

The plugin offers various features such as auto-conversion, custom cloze creation, cloze hints, fixed width options, and customizable editor menus. Additionally, you can customize the appearance of clozes with CSS variables. Overall, this plugin is designed to help you effectively review and retain information in your Obsidian notes.
