-For animation, moves should contains "moving" and "fading" maybe...
-(But it's really just for Magnetic chess)
-setInterval "CRON" task in sockets.js to check connected clients
-(every 1hour maybe, or more)
-Systematically show init+dest squares in PGN, maybe after short notation
-(2 moves list, second for de-ambiguification)
-Button to show all pieces that can move (next to expert mode; change icons)
+Implement Wildebeest castle rules
+=> (1, 2, 3 or 4 squares slide; randomized: may be impossible >1, but possible >4...)
-Bugs, limitations:
- - switching chess when castling: show 2 promotion kings (??)
- - Crazyhouse: TODO = keep track of promoted pawns.
- - Checkered: implement stage 2 ?!
+Embedded rules language not updated when language is set (in Analyse, Game and Problems)
+If new live game starts in background, "new game" notify OK but not first move (not too serious however)
+On smartphone for Teleport, Chakart, Weiqi and some others: option "confirm moves on touch screen"
+(=> comme pour corr) + option "confirm moves in corr games"?

+https://boardgamegeek.com/boardgame/18661/alapo
+Alapo is a strategy game. Each player owns twelve abstract pieces, two each of six different kinds. Round pieces move in any of the eight directions on the 6 by 6 board; square pieces move only orthogonally and triangular pieces only diagonally. Large pieces move any distance, small pieces only one field per turn.
+Opponent pieces can be eliminated by moving onto their position. The goal is to reach the opponent's base line with one of your pieces without the opponent being able to eliminate your piece in his/her next move.
