sometimes my particle systems (especially if they include ribbons) get really hard to see glaring issues because they move so fast.
im really hoping you could add a Pause button to stop the progression of the particle system just so i could get a closer look at the way things are at that moment. even better would be a way to pause at a specific time from start of particle system, EX. cause the whole system to pause at 1 second for me to check out stuff, change some values, click restart sim and it pauses again a 1 second in for me to see changes.
at the very least a play slow would be cool, play at half speed, quarter speed, eighth speed.
i understand theses are probably huge requests and possibly not that required by other people, but i could see it being really helpful.
