I think voting system would be great.
I also find this a source of frustration, which limits my desire to work on taxon photos.

There is a connected feature request, but I think voting would be better…
at the very least, limiting it to users with a certain number of IDs / observations.
Notifications wouldn’t hurt.
Reverting changes sounds good too…
As well as adding reasoning for change.
Be great to see this further developed!..but yes, the addition of history has been really helpful at least.
