Ok, I tried the windows version. Great stuff. Two suggestions:
- The pre-warm feture: not sure what it does. I expected it to pre-render a few timesteps so that the first frame is already a “fully-grown” effect. This would be very welcome
- To make a looping animation, you have to delete the start frames one by one (afaik). Would be nice to have it such that you can click a frame and select “delete all previous”
- An option to select between black and white as the particle color
