I have 60 explorers and 46 geos and maintaining takes most of the time i have to play, leaving less time for adventuring.
So much time is spent sending and waiting on geos and explorers.
To cut down time maintaining the island we need an auto-search setting that could be on or off on each geo and explorer.
This would allow the specialists to repeat the last search upon returning, until the button is turned off.
Another alternative would be to send them like gens to an adv. Select search type and select which ones to send.
