The Mastodon Threading plugin allows users to compose and post threaded content to Mastodon directly from Obsidian. It simplifies the process of creating and managing long-form posts by automatically inserting thread separators, visualizing post limits, and ensuring compliance with Mastodon’s size constraints. Users can attach media, add accessibility descriptions, and set post visibility preferences. The plugin connects to a user’s Mastodon instance, securely authenticating through OAuth. It also provides commands for sending single posts, managing separators, and submitting entire threads efficiently.
