 ImGui allows you create elaborate tools as well as very short-lived ones. On the extreme side of short-liveness: using the Edit&Continue feature of compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, etc. 
 
+Demo

+You should be able to build the examples from sources (tested on Windows/Mac/Linux). If you don't, let me know! If you want to have a quick look at the features of ImGui, you can download binaries of the demo app here.

-The bulk of example user code is contained within the ImGui::ShowTestWindow() function. It covers most features of ImGui so you can read the code and call the function itself to see its output. Ready-to-go example applications covering different versions of OpenGL/DirectX are provided in the examples/ folder.

 <b>How do you use ImGui on a platform that may not have a mouse or keyboard?</b>
 
-I recommend using [Synergy](http://synergy-project.org). With the uSynergy.c micro client running on your platform and connecting to your PC, you can seamlessly use your PC input devices from a video game console or a tablet. ImGui allows to increase the hit box of widgets (via the _TouchPadding_ setting) to accomodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse to allow optimising for screen real-estate.

 <b>Can you create elaborate/serious tools with ImGui?</b>
 
-Yes. I have written data browsers, debuggers, profilers and all sort of non-trivial tools with the library. There's no reason you cannot, and in my experience the simplicity of the API is very empowering. However note that ImGui is programmer centric and the immediate-mode GUI paradigm might requires a bit of adaptation before you can realize its full potential.

 <b>Is ImGui fast?</b>
 
-Down the fundation of its visual design, ImGui is engineered to be fairly performant both in term of CPU and GPU usage. Running elaborate code and creating elaborate UI will of course have a cost but ImGui aims to minimize it.

-If you intend to display large lists of items (say, 1000+) it can be beneficial for your code to perform clipping manually - using helpers such as CalcListClipping() - in order to avoid submitting them to ImGui in the first place. Even though ImGui will discard your clipped items it still needs to calculate their size and that overhead will add up if you have thousands of items.

+/*! @defgroup native Native access
+ *
+ *  **By using the native access functions you assert that you know what you're
+ *  doing and how to fix problems caused by using them.  If you don't, you
+ *  shouldn't be using them.**
+ *
+ *  Before the inclusion of @ref glfw3native.h, you must define exactly one
+ *  window system API macro and exactly one context creation API macro.  Failure
+ *  to do this will cause a compile-time error.
+ *
+ *  The available window API macros are:
+ *  * `GLFW_EXPOSE_NATIVE_WIN32`
+ *  * `GLFW_EXPOSE_NATIVE_COCOA`
+ *  * `GLFW_EXPOSE_NATIVE_X11`
+ *
+ *  The available context API macros are:
+ *  * `GLFW_EXPOSE_NATIVE_WGL`
+ *  * `GLFW_EXPOSE_NATIVE_NSGL`
+ *  * `GLFW_EXPOSE_NATIVE_GLX`
+ *  * `GLFW_EXPOSE_NATIVE_EGL`
+ *
+ *  These macros select which of the native access functions that are declared
+ *  and which platform-specific headers to include.  It is then up your (by
+ *  definition platform-specific) code to handle which of these should be
+ *  defined.

-/*! @defgroup native Native access
- *
- *  **By using the native API, you assert that you know what you're doing and
- *  how to fix problems caused by using it.  If you don't, you shouldn't be
- *  using it.**
- *
- *  Before the inclusion of @ref glfw3native.h, you must define exactly one
- *  window API macro and exactly one context API macro.  Failure to do this
- *  will cause a compile-time error.
- *
- *  The available window API macros are:
- *  * `GLFW_EXPOSE_NATIVE_WIN32`
- *  * `GLFW_EXPOSE_NATIVE_COCOA`
- *  * `GLFW_EXPOSE_NATIVE_X11`
- *
- *  The available context API macros are:
- *  * `GLFW_EXPOSE_NATIVE_WGL`
- *  * `GLFW_EXPOSE_NATIVE_NSGL`
- *  * `GLFW_EXPOSE_NATIVE_GLX`
- *  * `GLFW_EXPOSE_NATIVE_EGL`
- *
- *  These macros select which of the native access functions that are declared
- *  and which platform-specific headers to include.  It is then up your (by
- *  definition platform-specific) code to handle which of these should be
- *  defined.
