The Mention Things plugin introduces a flexible way to create mentions in Obsidian notes using customizable trigger characters like '@' or '#'. It enhances note-linking by offering suggestions based on the typed character and search term, allowing users to link people, projects, or any custom category with ease. Settings allow fine-tuning of matching behavior, character triggers, and input restrictions, making it highly adaptable to different workflows. Once a mention is selected, the plugin creates a properly formatted link and places the cursor conveniently for continuous writing.
