The Add links to current note plugin enhances note connectivity in Obsidian by enabling users to automatically append links to the currently open note at the bottom of selected notes containing wiki links. It simplifies the process of cross-referencing notes, making it easier to maintain a well-linked knowledge base. Users can execute this feature through the command palette or set a hotkey for quicker access. Additionally, the plugin offers an option to add links from the quick switcher, streamlining navigation and organization within the vault.
