title: How can I stop the UI from freezing?
body: <p>When I add many items to Canvas why does the UI freeze? Say I have a loop from 1 to 1000. I can only see all the elements after all 1000 of them are added. Why doesn't the Canvas show up items as they are added or removed one at a time?</p>
  
  <p>What can I do to achieve this effect? I want to animate the elements as they are added to Canvas one by one at a time. But the animation doesn't show up because the UI just freezes.</p>
  
  <p>Thanks in advance:) </p>
