# Busy and Stop

With `busyAction: "stop"` the host's `pending` state no longer dims or blocks the composer: the user keeps typing the next message while an answer streams, and send is replaced by the basic `XWUIStopGenerationButton` (`onStop` fires when it is pressed). A send attempted while busy is ignored. `sendStyle: "label"` prints `sendLabel` instead of the round arrow, on the stop control too.
