Clicking the Issues tab should show open issues
The Issues tab in my repository has a helpful count of open issues displayed in it. To me, this means that it is primarily about open issues, which it should be, since open issues are the important ones. But when I click a tab that says "Issues (2)", I expect to see a page that displays 2 issues. Today, it takes me to a page showing 5 total issues, with 2 open ones. I think the default action for the Issues tab should be to show only open issues. This is what most people need to see, and will align the page contents with the tab label.
