What is the best way to see what Diplomacy and Sanctions cards are in effect?

View Active Cards and History are the only two that come to mind, but in large team games, it is difficult to wade through these.

If diplomacy affects attacks between you and another person, you see a "D" next to your name.

However, if diplomacy is between 2 different people, you would have to see it in the above two methods.

Would it be a good idea to have:
A Different Colored "D" in front of their name to indicate there are diplomacy restrictions, and hovering over would give details?
An "S" indicator that Sanctions has been applied to someone. Additionally, this "S" indicator could be carried over to the Statistics Graph, perhaps by using a different marker on the datapoint, an x, rather than a dot?

That`s a great idea! I suggest you put it up to User-voice :)

yeah, good idea. please submit it to uservoice.
