A simple idea to help DMs would be hotkey or key modifier hooks put into the turn tracker window to aid in selecting or finding the tokens who's turns are active. Sometimes in battles with multiple similar NPCs, the battle gets shuffled and it gets hard to locate the particular tokens amongst the jumble. The yellow box mouseover effect is very useful, but even that is limited to tokens that are visible on the screen at the time. Example 1: Click or Double-click a unit in the initiative window to select the relevant token. Example 2: Shift-Click so that the targeted token is focused or pinged.
