   1 PROBABLY WON'T FIX:
   2 Embedded rules language not updated when language is set (in Analyse, Game and Problems)
   3 If new live game starts in background, "new game" notify OK but not first move.
   4
   5 NEW VARIANTS:
   6 https://www.reddit.com/r/TotemChess/comments/imi3v7/totem_rules/
   7 --> replaced by "Joker" chess --> start on bishop of our color (instead),
   8     moves like a Bishop + Dabbabah, can swap with a piece *on same color* (as a move) at anytime. hmm
   9     or rather: start as in Antiking + Mesmer, in front of. moves like an amazon. swap with any color. better!
