I would like to suggest the implementation of an easy shortcut to access the last 10 (for example) questions that I have participated in (answered or commented on). This could be implemented as a dropdown in the top menu. Currently I have to go to my profile, and click on the "activity" pane. However, what I'm presented with here is polluted with rejected/approved edits and other "irrelevant" stuff, and thus makes it hard to easily find those questions that I'm "participating" in.
Let me know what you think.
