Some things id like to see
Cow tops, No pants shirt, and some other non onesies option for being decent with Mega Boobs
some sort of character quest tracker, (Cause i don't know where I am in Gin's quest, and I don't know what events i've seen)
The option to use the Growth spells to go Mega, like after you gotten them once and have succubus powers
Advanced Arm & Leg splash, like it goes up to your Knees/elbows or half way past them
