+Animal detail slider, event timeline, I want to be able to click on events and go to a detail view about them.
+
+Create animal cohort form, click button, succeeds, comes back to the same form when successful. There should be a notification that it worked and link to detail view of the event created. Audit all other forms for this.
+
+If I want to sell 2 ducks matching "species:duck sex:female status:alive", how do I do it? The record outcome form says 35 animals selected if I use that filter.
