A nice to have feature, in maps choose to show different things, fx dives from one type of tagged dives, or for each diver or dives dived in a specific time etc.
But otherwise a really nice app/software you here have
I would need to have a think about how to implement this. Are you referring specifically to macOS, or iOS?
My first thought (for iOS) is to have a map available from each dive list, which would give you the ability to do that for almost anything from any tag, smart log, gear, etc.
I will add something to my TODO list to look in to this.
