One technique I lifted from another module recently was to give every
card in my game a Marker trait with a value--e.g., CardCount=1. My Game
Piece Inventory Window shows only things on the 6 player hand "maps",
then displays the folder label as follows: $CurrentMap$ =

In my case I'm actually tracking the number of two types of cards, so
it's slightly more involved, but that's the basic idea. If there is any
chance whatsoever that something other than a card will ever end up in
the player's hand, it needs to get the same Marker with a value of 0,
I've discovered--quite bizarrely, the technique I described will add 1
to $sum_CardCount$ even if a piece without that Marker is present. So in
my case, where I'm tracking basic event cards *and* home cards, they all
have to get a Marker for both types: event cards get CardCount=1 and
HomeCardCount=0, and home cards get the reverse.
