Something simple I would like: The ability to make a group or item “hidden”, or invisible, the same way I can make files invisible to the Finder. There would then be a global toggle option for ‘Show invisible’.
The reason I want this is that I have a huge database of financial documents, separated into categories like Banking//. After a while, some of these institutions become stale, as I’m no longer associated with them and their contents are getting a decade or more old. Rather than having to maintain a second, parallel hierarchy for “retired” groups, I’d like to mark the uninteresting groups as invisible, since odds are I won’t want to refer to them 99% of the time.
I’d still like their contents to show up in search results, however, unless I check a Preferences option named “Hide invisible items from search results.”
