Right now if you click on a TDM server in the list, the scoreboard preview shows on the right column and you can see the current number of kills for each time and a progress bar that can give you an idea of how many tickets there are in total (those are native Battlelog features).
But it would be nice to know exactly the number of tickets of the round, if you go on the full server page you can find this information (above the scoreboard), so would it be possible to have the same information on the scoreboard preview (right column of the server list) once you've clicked on a server?
