Flaws in diplomacy tab for messaging

Not many seem to have discussed the diplomacy tab, so I'll start.

First, it's hard to point out provinces, directions, military units, time, and such in diplomatic messages. This makes it hard to coordinate with players if they don't know how to look it themselves or familiar with the jargon of CoW.

Second, it can be rendered useless with people communicating with other methods. Though, this may be an early remark since the survey is still ongoing.

Third, no one seemed to say about this before but, if you use diplomacy for messaging private affairs--as in non-CoW stuff--it can leak to other players by spies. My spies have shown me something like those a few times before, and that was kinda awkward, I don't think they even realized about this possibility.
