Filter on Author should include all Authors in the issue list, not just members of the project.
Need the ability to create a filter for issues where the author is no longer a member of the project.
In models/query.rb the list of users for the author filter is built from the principles of the project. This excludes users that are not members of the project (either the user was removed as a member, or the issue was moved to the project)
Request: Update the Author filter for issues to use the list of Issue authors instead of the project members
(I believe that the Assignee filter is also built in the same fashion).
