Thank you @bouteloua for moving my post into this thread. I did a brief search for other notifications-related topics but somehow missed this thread of wonderful ideas (apologies for repeating what others had already said).
I’m excited to see that the notifications system is getting upgraded. One thing I haven’t seen mentioned yet in the notification wish-list is being able to control them by taxon. For example, I like to see notifications for confirming IDs for taxa I’m not as confident on, but I don’t need to see them for the umpteenth western sword fern I’ve identified.
