Suggesting a Highlight or Mark feature be added.
On some large maps when you are attempting to describe which space you are referring to - sometimes it is difficult for the other player to know which space it is.
The Highlight feature would allow you right click (or somehow select) one space and it would be highlighted for all to see.
You could then say - "hit him with that 8" or "place a shield on your marked 1!"
Could be particularly useful on the largest maps.
