  Q: I integrated ImGui in my engine and some elements are clipping or disappearing when I move windows around..
- A: Most likely you are mishandling the clipping rectangles in your render function. Rectangles provided by ImGui are defined as (x1,y1,x2,y2) and NOT as (x1,y1,width,height).

  Q: Can I have multiple widgets with the same label? Can I have widget without a label? (Yes)
  A: Yes. A primer on the use of labels/IDs in ImGui..
