  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..
- 
+
    - Elements that are not clickable, such as Text() items don't need an ID.
 
    - Interactive widgets require state to be carried over multiple frames (most typically ImGui often needs to remember what is the "active" widget).
      to do so they need an unique ID. unique ID are typically derived from a string label, an integer index or a pointer.
