SImply Great. Out of other programs for such tasks, this one is very simple at the same time very very effective.
Crashes a lot. And the editor window doesn't show up correctly - people seem to use mostly the random features so they don't bother to use the editor but I was trying to recreate a flame from the parameters of UltraFractal and couldn't do it because the editor window is all messed up.
