Maybe it's just me being clumsy but I've had a few instances where I've accidentally selected the "all" button while playing with my mouse because that is the first thing that gets highlighted when selecting things like dropping/donating/feeding ect.... sometimes even when I input an amount the "ALL" button still prevails... perhaps a button for the quantity picker for people who play with the mouse because there's no way to confirm with a mouse!
I'll be more careful though obviously :] just wondering if anyone else has been clumsy like me
ORRR
The main reason I play with a mouse is because of the chatting! If there was a button/key that would open up chatting or something I would play with the keyboard!
