The Auto Split plugin enhances the Obsidian workspace by automatically opening notes with the editor and preview displayed side-by-side when no other files are open. This feature is especially useful for users who prefer to see their edits reflected instantly. The plugin also introduces a command to split the current pane into two linked panes, allowing users to edit and view their notes simultaneously. It only works on desktop and tablet devices, as split panes are not supported on mobile phones. The plugin is designed to operate efficiently, activating only for Markdown files and ensuring existing files are not disrupted. Users can configure platform-specific settings to enable or disable the feature as needed, making it a flexible tool for multi-device workflows.
