The Unitade plugin for Obsidian provides a versatile solution for managing file extensions within the app. It allows users to open and edit files with custom extensions, something that is not supported by default in Obsidian. The plugin enables rendering files with various extensions as code, similar to editors like VS Code, and offers compatibility modules for older plugin versions. Users can configure the plugin to handle specific file types by entering their extensions in the settings. Unitade is designed for those who want to expand Obsidian's capabilities and streamline the process of working with non-standard file types in their vault.

The Custom File Extensions and Types plugin enhances Obsidian by allowing users to associate specific file extensions with different in-app view types through customizable settings. It enables seamless editing and configuration of file extensions, including options for mobile-specific settings and overriding default behaviors. Users can assign various extensions like `.txt`, `.html`, or `.yaml` to the markdown view or other registered views, ensuring greater flexibility in managing files. The plugin includes tools for debugging and viewing all current file extension associations, providing clarity and compatibility with other plugins. Extensions are case-insensitive, and real-time updates ensure immediate application of changes.
