I think it would be nice to allow to paste/enter multiple participant ids separated by comma into the "add participant" dialog box. The list will be parsed/validated by the client and interpreted like it the user added these participants one by one. This way it would be easier to create waves with multiple participants.
The code is handled in ParticipantController.
