From About the Bug Reports category:
“By “bug” we mean that something is not working the way it is intended to. This is not a place to make a feature request (there’s a separate category for that), nor is it a place to start a discussion about how iNaturalist does things - you can do that in the General category.”
This is an intended feature and is explained here: https://forum.inaturalist.org/t/add-number-of-photos-to-thumbnails-on-identify-page/2907/14 So it doesn’t belong in Bug Reports. I’m moving it to General, and I also added “I” to the subject.
Maybe it’s just me, but I’m not sure terms like “I hate it” are helpful. If you dislike something, please state why and propose a solution.
