You can kind of already do this with filters but I find that interface cumbersome. I really like the search box in the upper right hand corner but it doesn't allow me to limit my results to the current releases showing on the Feature Board. When you have a lot of features and releases it can be hard to find things and this would help with that.
Thank you for the note. As you mentioned, this functionality is available through the Filters on the feature board page.
It's also possible to leverage the Report pages to create views that you are interested in as well.
At this time, we do not have plans for additional revisions in this area based on existing functionality and current priorities. We hope you can understand.
