-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)
+# Functionality:
+On Game page "mconnect" events =>
+ send lastate to them (because they have the game infos) or just "your turn" - if their turn
+ remember them to send next "newmove" (or just "it's your turn") later - if not their turn
+ (=> listen for "mdisconnect" as well)
+From MyGames page: send "mconnect" to all online players (me included: potential multi-tabs)
+ When quit, send mdisconnect (relayed by server if no other MyGames tab).
+And remove current "notify through newmove" on server in sockets.js
