In every user page we can see a paragraph about the projects in which the user is most involved with. We can see the rosetta icon, the bug tracker icon, blueprint icon etc. depending on the work done by the user. If I am interested to see what the user has done, I should be able to click on the icon uder the paragraph "most active in" and get redirected to the Bug list reported by the user (clicking on the bug tracker icon), to rosetta (clicking on the rosetta icon) and so on.

This idea is really for launchpad and not ubuntu, but here it goes.

It would be cool if there was a counter for duplicated bug reports for the simple reason that with a counter we could see how many times the different bugs get reported and maybe with that information prioritize the bugs.
