It would be nice if we could limit the achievements view to the current site only. The current view list everything globally.
Now it would be nice if we would have the option (f.e. with tabs) to limit these to the current site, like in this bad mock-up.
The background is that I always used the (old) reputation-dropdown-from-username to determine what was going on with my stuff, on the current site (f.e. editing/updating old answers which suddenly got attention).
