The S3agle plugin enhances file management in Obsidian by integrating S3 storage and the Eagle file management app. It enables seamless uploading of files to S3 or Eagle, creating preview links and managing local or remote file storage. Users can configure settings for automatic uploads, drag-and-drop functionality, and selective local-only storage. The plugin supports embedding files such as PDFs and PowerPoints using external viewers and includes options for file name hashing for privacy. With commands for bulk uploads or downloads and the ability to handle files across platforms, S3agle simplifies file organization and retrieval for Obsidian users.
