anyone that uses anything like photoshop would know of the neat things called "add-ons"

add-ons extend the capability of a software beyond the original capabilities of the software and the manufacture updates.

and i was quite obsessed with finding them before but now i'm on the hunt again XD

anyone know of any good and useful ones they could recommend? preferably free trial ones (i decided i would start whipping my hard drive every 29days to combat my inability to pay for software, since i have an external hard drive to store ALL of my files ^_^)

so essentialtty even though their free trails it will be as if i own them ^_^ which is handy being i'm studding graphic design.

thanks in advance ^_^
