Can ImGui manage the Main Viewport?

Version/Branch of Dear ImGui:

Version v1.91.6, Branch: docking

Back-ends:

imgui_impl_Custom.cpp + imgui_impl_GLFW.cpp

Compiler, OS:

Windows 10 MSVC/Clang

Full config/build information:

No response

Details:

Is it possible to make ImGui handle the Main Viewport (GFLW Window)? Im talking about resize and drag.

I want to make a custom title bar, but that is just not possible with GLFW, the only option is disabling decorations entirely. Good, but then i lose Resize and Move. Is it possible to manage the window with ImGui? Or am i stuck with forking a GLFW? Should i just calculate and handle resize/move with ImGui myself?

It's not possible yet but I eventually want it to happen.
