Breadcrumbs
Bugtracker of sorts working off source code.

Cmd + R to refresh the list
Up/Down to navigate issues
Double click a category to toggle its visibility.
Open in Xcode opens the file in Xcode at the line of the current crumb.
Hashtags in a crumb comment are parsed, click a tag to filter the issues.

The search field filters crumbs by a keyword.
