I would find helpfull, when you are warned about another empire get a milestone, to have some kind of boxes (like the personal victory screen/tab -- F1 then victory tab -- milestone) on which milestone the empire/alliance has.

For exemple, the 1st warning screen could have a full square blinking (and some empty boxes), 2nd warning could have a full box, a second box blinking, a remaining empty boxes, and so on.


As for now, without writing it on paper or somewhere, you don't know which milestone does the empire has.

And by with way it goes worse then alliance are created somewhere and then new messages are given, you really don't know where they are exactly.


Perhaps too you could unlock this improvement in a science tech that already exist.
