 ### Integration
 
-On most platforms and when using C++, **you should be able to use a combination of the [imgui_impl_xxxx](https://github.com/ocornut/imgui/tree/master/examples) files without modification** (e.g. `imgui_impl_win32.cpp` + `imgui_impl_dx11.cpp`). If your engine supports multiple platforms, consider using more of the imgui_impl_xxxx files instead of rewriting them: this will be less work for you and you can get Dear ImGui running immediately. You can _later_ decide to rewrite a custom backend using your custom engine functions if you wish so.

 Integrating Dear ImGui within your custom engine is a matter of 1) wiring mouse/keyboard/gamepad inputs 2) uploading one texture to your GPU/render engine 3) providing a render function that can bind textures and render textured triangles. The [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder is populated with applications doing just that. If you are an experienced programmer at ease with those concepts, it should take you less than two hours to integrate Dear ImGui in your custom engine. **Make sure to spend time reading the [FAQ](https://www.dearimgui.org/faq), comments, and some of the examples/ application!**

 ### Upcoming Changes
 
 Some of the goals for 2020 are:
-- Work on docking. (see [#2109](https://github.com/ocornut/imgui/issues/2109), in public [docking](https://github.com/ocornut/imgui/tree/docking) branch)
-- Work on multiple viewports / multiple OS windows. (see [#1542](https://github.com/ocornut/imgui/issues/1542), in public [docking](https://github.com/ocornut/imgui/tree/docking) branch looking for feedback)
-- Work on gamepad/keyboard controls. (see [#787](https://github.com/ocornut/imgui/issues/787))
 - Work on new Tables API (to replace Columns). (see [#2957](https://github.com/ocornut/imgui/issues/2957), in public [tables](https://github.com/ocornut/imgui/tree/tables) branch looking for feedback)
+- Work on Docking (see [#2109](https://github.com/ocornut/imgui/issues/2109), in public [docking](https://github.com/ocornut/imgui/tree/docking) branch)

+- Work on gamepad/keyboard controls. (see [#787](https://github.com/ocornut/imgui/issues/787))
 - Work on automation and testing system, both to test the library and end-user apps. (see [#435](https://github.com/ocornut/imgui/issues/435))
 - Make the examples look better, improve styles, improve font support, make the examples hi-DPI and multi-DPI aware.
