Hiding the main window

[ShamaIow]

Version/Branch of Dear ImGui:
Master branch, dear imgui, v1.89.2

Back-end/Renderer/Compiler/OS
Windows, Visual Studio, DX11 / Win32

My Issue/Question:
So after search for like 2 days i can't even find a project detailing how to delete this main window or hide it and only display the ImGui in it, like a docking without the main window.

Screenshots/Video
The screenshot show a DX9 project but mine is DX11, i only want to keep the TEST OVERLAY without the Dear Imgui DirectX9 Example window

Standalone, minimal, complete and verifiable example: (see #2261)

Step 1: Download the master branch
Step 2: In your project, create a folder named "imgui" and then extract everything from the zip you downloaded into the imgui folder you created
Step 3: Now you have all the files, go into the "examples" folder and delete everything else then the following files / folders:

• example_win32_directx11 (foler)
• libs (folder)
• imgui_examples.sln (file)

Step 4: launch the imgui_examples.sln file, ignore the popup telling 99% of the example disappear magically and start the project by pressing F5

---

The goal: Once you got the blue window with the 2 test gui inside it, the goal is to get the 2 gui (or at least 1 of them) without having the blue background window, be sure you can move your gui(s) everywhere on your desktop.

Hello,

Please note that the area you are trying to remove is not created nor maintained by dear imgui.

This is the same as #3680.
It's not currently supported, I suppose it eventually will be.
My main problem with this feature is that it'll attract a lots more users coming from a making-desktop-app background (rather than in-game/engine overlay background) and I'm not looking forward to the support requests, especially since multi-viewports support has too many subtle issues and more people reporting issues than putting work into fixing things. So I wouldn't be in a hurry trying to cover the "no user-created main viewport" case.
