The Douban plugin allows users to import and manage content from Douban directly within Obsidian. It supports importing various types of media, such as movies, books, music, TV shows, diaries, and games, along with user-specific data like ratings, comments, and watch/read status. The plugin enables synchronization of personal records, saving media covers locally or to an image hosting service, and customizing templates and file organization. It also integrates with other Obsidian plugins like Timeline and themes to enhance visualization.
