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 modern 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

Binaries/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 Windows binaries of the demo app here.

// ImGui - binary_to_compressed_c.cpp
// Helper tool to turn a file into a C array.
// The data is first compressed with stb_compress() to reduce source code size.
// Then encoded in Base85 to fit in a string so we can fit roughly 4 bytes of compressed data into 5 bytes of source code (suggested by @mmalex)
// (If we used 32-bits constants it would require take 11 bytes of source code to encode 4 bytes.)
// Useful if you want to embed fonts into your code.

// (If we used 32-bits constants it would require take 11 bytes of source code to encode 4 bytes, and be endianness dependent)
// Note that even with compression, the output array is likely to be bigger than the binary file..
// Load compressed TTF fonts with ImGui::GetIO().Fonts->AddFontFromMemoryCompressedTTF()
// Single file application, build with:
// # cl.exe binary_to_compressed_c.cpp
// # gcc binary_to_compressed_c.cpp
// etc.
// You can also find a precompiled Windows binary in the binary/demo package available from https://github.com/ocornut/imgui
