The .md Merge plugin simplifies the process of consolidating multiple markdown files into one neatly combined document. It scans a chosen folder and, if needed, dives into subfolders to collect every .md file, then merges them into a single output file. Users can fine tune the process by excluding specific files with glob patterns, skipping hidden notes, or even customizing the output filename with date-based templates. The plugin quietly handles folder creation if the destination doesn't exist and offers quick access through a sidebar button, command palette, or hotkeys.
