I wish there was! Unfortunately, Things content can’t be queried from outside Things, so that isn’t possible.
One thing I have been considering, though, is a branch for “bookmarks/saved links”, where you could maintain a list of links to useful stuff you link back to a lot (a very popular project, a commonly visited webpage, etc.), so that might be a viable workaround to use for Things areas or Things-related links that are less ephemeral?
Thanks for taking the time to check this out, Ben!
