I think that as a matter of security (in the Firesheep age) I'd like to see the last IP address from which my account was accessed next to my name, somewhere in the top bar. I'd also ideally like a history of my IP addresses (available only to me) in my account summary.
Thoughts?
EDIT:
Right now, it shows the "last activity from xxx.xxx.xxx.xxx N hours ago." or "Last activity from this IP address N hours ago."
I want two changes. Firstly, I want to see the last IP address even if it's the same one, as in: "Last activity from this IP address (xxx.xxx.xxx.xxx) N hours ago.)
Also, I want a new tab with all of my recent IP addresses, similar to Gmail.
