[FEATURE]: Update preview window when not attached to editor #34
Description
When opening a file directly in the preview window, any file updates are not reflected in the preview as it does not use the built-in file watcher. If the preview is attached to a standard editor window, then as that window updates, so does the attached preview.
This matters when using VSCode to monitor a log file constantly being appended. It would be great if a detached preview window continues to watch for file changes and updates.
