Maybe it shouldn't be a surprise, but the Finder window sidebar seems to accommodate anything.
TIP: Is there a web site you'd like REALLY fast access to, without opening the browser, bookmarks, etc?
- Save the url as a separate file and add it to the sidebar. - Either drag it in, or use the Finder menu File/Add to Sidebar.
Handy for a web support page for a new device, for example. - And any number of other uses.
THE CATCH: The url file has to stay on your drive somewhere. If deleted, the sidebar item goes with it.
