think they should be visible in mini profile
for example if Y is an alt of X i should be able to know it without checking the private notes each next time i forget
or if someone is a noob or i just don't like them,or i think they start only in partha in RoR or someone is expansionist,etc i wont check their profile every time i play with/against them

That would actually be helpful... private notes aren't very player-friendly

Even if it just colored the private note button (like when someone is a friend). Right now you can make notes on the person and it does not even color the button.
