A neat trick is that the top search here https://secure.phabricator.com/search/query/edit/ influences the native global search. This is cool if you really only want to search tasks...unless you specifically say. But it's not clear that the relationship exists and since a new saved search is placed at the top there users keep messing up their global search by saving a custom search for a particular thing.
(When they influence their global search by say limiting it to a project or something it is really confusing and was aptly described yesterday as "black magic")
- Make a new saved search insert at the bottom of the list so it doesn't hijack global search by default?
- Put some text or indication on /search/query/edit/ that the top search will change how global search works?
There would be much rejoicing.
