Display the first 4 chars of a SessionId in the Session Selector

Description

This is how it looks if I do many similar stuff.
Clearly hard to distinguish. I suggest also showing the first 4 chars of the SessionId.

This is an interesting idea. Not opposed to this, but maybe a relative date would be better? i.e. 30s ago, 5d ago, etc.

Also, per our community guidelines, I'm converting this to a discussion. We we agree it's something we want to go ahead with, I'll convert it back to an issue.
