I report you here one demand there is within hex players about the game, and another one I have but that corresponds to a reality we're all facing.
The first one is to have figures around the board to see easily the different grids. It's good to name moves for instance, to speak with the opponent after a match, to explain to a beginner... A lot of players claims for that (little) in the interface of hex. In addition to that, one argued about changing the names of the moves, so that the columns would be then represented by letters and not by numbers anymore. It can get easier to represent it to mind indeed, plus it's more common in other cases to see this convention than the all-numbers one.
The second one I had idea from a discussion about Alveole. The one who developped the game was thinking about creating a special option "missclick", which would allow a player to let his opponent play to change their last move because missclick. This would be very useful in hex. Somtimes big players lose because of that, and not all accept to play a bad move or to make a collective concede.
Thanks for your attention
