-[Sittuyin (burmese chess) --> probably not]
+PROBABLY WON'T FIX:
+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.
+
+"FreeBoard", re-using a lot of Board logic, but with SVG (empty) board + SVG (empty) reserves.
+Will be used for variants with custom non-rectangular board (Hex, at least)
+Or, with other board shapes (see greenchess.net for example)
