Description

It would be good if there is a possibility to filter for all not already assigned issues. In repositories with many issues we keep the issues open until the PR got merged, so if many PRs are pending, the issue list is full with issues assigned to some persons which are typically done. (They get closed automatically once the PR is merged.)

So as maintainer I would like to filter all issues which are not assigend yet, to get all tasks without any progress. This would be good.
