in the aoe3 original the asian dynasties, whenever you used the Find Explorer keybind (by default “/” in legacy), it would take you to the Japanese monk (explorer), and if you pressed the Find Explorer keybind again while having the explorer monk selected, it would alternate to the SECOND Japanese monk.
as of now, it’s stuck on only one explorere and i think it’d be nice to be able to swap back and forth between the japanese exploreres specially when trying to split them for a shrine boom. of course, there’s always the option to control/shift group them separately but it was nice to not have to keybind them on control groups.
