usefulness, ease of use, power lol- not- but it is still easier then almost all of the other apps. no matter what- you'll have to spend time and some money to achieve what you want. like painting, skills are involved that not every one has. there is no 'press make art' button there is more to be said but I'm sure others will, I won't blow smoke up your butt and say anyone can do it and will be great.
