 That branch contains two important features: [multi-viewports](https://github.com/ocornut/imgui/issues/1542) and [docking](https://github.com/ocornut/imgui/issues/2109).
 
 Even if the viewport feature is still in a very experimental state, yet the docking API seems pretty stable. Thus, imgui-java exposes it and hides everything about viewports.<br>
