maxVisibleMembers property
Caps how many member avatars the turn tracker draws before folding the
rest into a +N overflow disc.
null (the default) means "as many as fit the card": the tracker
measures its own width and folds the remainder. It never scrolls and
never runs off the edge, which is what used to swallow the seventh
member of a circle without leaving a trace that they existed.
Implementation
final int? maxVisibleMembers;
