Thanks for doing this. This new feature might be even more valuable if the list was limited to Discussions where users are looking for a response. Right now it includes other categories (Knowledge, Events, etc.) where a response is not always required.
Would also be good if the link was placed on the main menu where it is not so hard to find. Alternatively or in addition, each Discussion section could be given an option to show just those entries with zero responses.
Thanks for the additional insight @derekbelyea! I'm actually looking to consolidate all of the feedback we've received around filtering options into a single suggestion, and will make sure to incorporate your recommended improvements. I'll comment with a link to the suggestion as well, once it's available.
