Nothing crazy, a minor idea. Simple at that and probably not even to be noticed at most times. But I was just thinking that the "last action" category on your profile will only show when your last action was as a time. Why not escalate on that and add to that.
As an example...
Last Action: 2 minutes ago gambling at the casino
Or
Last action: Now (viewing the stock market)
These are just two small examples as an idea.
There is endless ways you could elaborate on this category. It's something simple but it could be a cool little change hahaha.
