Could it be possible to associate personal notes to another user? For example, I don't like to play private games, however, since most games are public, I don't often realize that at the invitation screen, so If by any chance I realized that in the middle of the game, I could associate a note to the user so that in the next time it would warn me that he might have sent me a private game request. Or if on a game where there is the possibility to choose the starting position (logik, battleboats, etc), and if I noticed a pattern on the first move of a certain player, I would like to associate a note to his username, so that the next time I would play him(her), I would avoid a game configuration that he would most probably choose.

I don't know if this is already possible with the notepad right now, since I don't use it much, but it seems to me that I have to remember to go there and see what is written, instead of something like "make this note visible if I play against ..."
