This is one of the main issue i have with this in comparison to Kanpani, it requires you to stay all the time on-screen.
On kanpani i start a quest. then do something else on another tab until the quest ends.

Since there is no user input other than the sunbean on battlers, i don't get why force people to be clicking during the map movement, if you don't have any control on it at all, such as choosing directions or managing your poarty.
