Product recently implemented a feature on the agile story boards that appear at the bottom called "show more stories." The issue is, even when filtering on a user, if your stories don't appear in the first 100 stories of the group, you need to expand the stories, even if the user has less than that. Additionally, the button appears very sneakily at the bottom of the page. But not just the bottom of your browser, you need to scroll to the bottom of the web page to do that.
This "idea" is to removed that "Show more stories" button and replace it with more filtering options at the top. Perhaps in addition to the user filter, you could create a custom filter for project name, hours, duration, etc.
