(1a) New iNatters, and possibly many iNatters in general, don’t know that.
(1b) The “Identify” page (showing 30 observations) does not even show if there is a placeholder.
(2a) iNat didn’t plan to change the placeholder:

(2b) Still waiting for this other “should be done” (unless I missed it) (unrelated topic, just an example):

I enjoyed doing things, as I could, instead of just waiting (for how long?) for new features to come.
