[Hall of Famer]

Well regarding advanced leveling, I am also thinking about this idea called level inheritance. When an admin creates a new adoptable without any new levels, he/she can choose an existing sets of levels from another adoptables as 'template'. This way the default required clicks for each level of this very new adoptable will be the same as the other adoptable used as its 'template'. Of course it only applies to properties such as maximum levels and required clicks, the adoptables primary/alternate images will differ and must be set manually by the admin.
