Too hard to see Overview of a bug's various affected packages

[LI Daobing]

for example, when I view following bug page[1], if I want to view the overview page of emacs21, I can just click the "Overview" link, but if I want to view the overview page of "fcitx", it somehow hard.

I think there should be a link to switch [1] to [2] and [3], so I can check the information of the related packages with one or two click.
