Just bought your tool. So far I am liking it. One small suggestion. Add a play from here button. That should make the experimentation with filters faster. As long as the previous step is rendered, there is no need to re-render it.
Thank you for your purchase! I'm glad you're enjoying the tool.
I appreciate your suggestion about adding a "play from here" button - this would improve the experimentation workflow. I'll add this to my development tasks.
