I finally got some time to implement something new. [1]
So, You can now click on the bug or test case and it will open new tab in your browser as you would expect.
Also, Bob Lightfood requested "fedora-easy-karma like" filter. If You now check "Karma not submitted" checkbox (under the installed packages), only those installed packages will be shown, for which user has not submitted any karma. You'll need to enter some username under that checkbox as well.
