hey, how about a new tool like a "select tool" and "find and replace"? "select" tool can turn on the "fan", and "find and repace" tool can replace anything by writing the element to be wanna replace it and write element to be wanna successor the element before (sorry to all if my english is bad )

allright, and how to active a "fan" ? ( )

emm, "find and replace" you can use it with a text, like [goo => wood] the goo in the game will transfer to wood
