Add more than just 'Rotate' and 'Grow'. Maybe 'Custom Path' or a 'Streak' effect

It's a good program, but theres nothing special about it. If they added more than the basic effects you can get on free programs, I believe it would be a better program. I like that it's "lightweight", but they could've made it a little "heavier" and it wouldn't have made a difference to many people.
