Safari: Can I open all bookmarks in a bookmark folder in a new window? Is it possible to open all bookmarks in a bookmark folder in Safari in a new Safari window? 

I know that I can do this with a single bookmark, but can I do the same with a bookmark folder?
Open the Bookmarks menu, top left, right click the folder of bookmarks, Open in Tabs...



Though irritatingly, it re-uses the current window, so maybe start with a new one first.
