-   - after calling ImGui::NewFrame() you can read back flags from the IO structure to tell how ImGui intends to use your inputs.

-     When 'io.WantInputsCharacters' is set to may want to notify your OS to popup an on-screen keyboard, if available.

       e.g. when displaying a single object that may change over time (1-1 relationship), using a static string as ID will preserve your node open/closed state when the targeted object change.
       e.g. when displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state differently. experiment and see what makes more sense!
 
+ Q: How can I tell when ImGui wants my mouse/keyboard inputs and when I can pass them to my application?
+ A: You can read the 'io.WantCaptureXXX' flags in the ImGuiIO structure. Preferably read them after calling ImGui::NewFrame() to avoid those flags lagging by one frame.
+    When 'io.WantCaptureMouse' or 'io.WantCaptureKeyboard' flags are set you may want to discard/hide the inputs from the rest of your application.
+    When 'io.WantInputsCharacters' is set to may want to notify your OS to popup an on-screen keyboard, if available.
+    ImGui is tracking dragging and widget activity that may occur outside the boundary of a window, so 'io.WantCaptureMouse' is a more accurate and complete than testing for ImGui::IsMouseHoveringAnyWindow().

  Q: How can I load a different font than the default? (default is an embedded version of ProggyClean.ttf, rendered at size 13)
  A: Use the font atlas to load the TTF file you want:
