ideas for improving the "something new is being shared with you" webpage

I'd like to suggest three improvement to the webpage that is being shown when you first click the link you get in e-mail when someone else shares something with you.

1) don't show that long UUID by default (hide it under an "advanced details" tab or something)
2) make it easier to understand what the "claimed:" field is used for, at first this is empty and for a new user it's hard to understand the purpose of it
3) also include the e-mail of the person who is sharing something with me (that's a better way to make the share info canonical compared to including the UUID).
