The Extended Markdown Syntax plugin enhances Obsidian’s markdown capabilities by introducing additional inline formatting options without relying on HTML tags. It supports underlining, superscripts, subscripts, and spoiler text, making formatting more seamless in both editor and preview modes. Users can also align paragraphs using special syntax, apply custom highlight colors, and ensure formatting remains context-aware by excluding code blocks, math expressions, and comments.

The Style Text plugin enhances text formatting in Obsidian by allowing users to apply custom CSS styles to selected text. Users can create and manage multiple styles through the plugin settings, which can then be applied via commands, hotkeys, or the context menu. This plugin offers flexibility in formatting with options to customize style order and accessibility. Additionally, a 'Remove Style' command is available to revert unwanted formatting changes easily. The plugin streamlines text styling, making it a valuable tool for personalized note organization and design.
