Hey folks - it's useful for us to be able to easily find Features that don't have Initiatives associated with them. But in the Releases Overview you can't filter to just show releases without initiatives.
Hey Danny - I get what you're saying, it's just surprising that a Filter doesn't have an option to say "show empty values". It's a pretty common filter pattern and one that would be useful - save the user the extra time and clicks to go create a report for something they're doing in their general workflow.
I saw this idea come through and wanted to jump in -- if you want to view your features that do not have an initiative the best place to do that would be through a list (Features > List or Reports > List) or similarly through a Report > Pivot. Features by Initiative is one of the example reports, so you can get a view like what you are describing out of the box through using that example.
The Releases > Overview is a release centric view, the filter options are allowing you to filter releases by different means; such as filtering releases by their related initiative. It would not be a screen to visualize the connection between features and initiatives as that relationship is not displayed on that page.
