So it could be a panel, window, or tab, with a palette of All Tokens to change the options. I see what you're saying it could be a pop-over window like Initiative Tracker (and conceivably this could be configured to ONLY show the Tokens that are on the map Page that you're currently on, rather than all Tokens in the game). However alternately I think it could be equally accessible as a new Tab over the chatroom, or a sub-section under the existing Journals tab (where Characters are already listed, there could be a new section of rows for Tokens).
