imgui

Currently looking for help with those things.
This is absolutely not a complete list (there a millions of other things to do, see Issues and docs/TODO.txt), those are merely some suggestions of things I am particularly struggling with before I may not have the hardware or expertise. If you are motivated and want to help this project and the community there is almost certainly a spot for you :)

Funding

If your company uses Dear ImGui, please reach to contact@dearimgui.com.

Documentation

The wiki needs improvements.
How about creating visual gallery showcasing external widgets?
We need features overview pages describing Gamepad/Keyboard Navigation, Docking, Multi-Viewports, Tables etc. for users.
We need technical overview pages describing the same but from the point of view of programmers wanting to work on them.

Community

Helping to answer some GitHub issues/threads or Discussions?

Third-party Software
If you are familiar or interested in GLFW, designing/developing/submitting those changes to GLFW would be great

Linux/Mac: implement per-OS workarounds for other GLFW/SDL issues, see https://github.com/ocornut/imgui/issues/2117#issuecomment-465185644
GLFW: Solve https://github.com/glfw/glfw/issues/1236 in GLFW (transparent inputs) for portable multi-viewport support. OR implement per-OS workaround in imgui_impl_glfw.cpp. Done PR: https://github.com/glfw/glfw/pull/1568, Waiting for GLFW merge.
GLFW: implement/solve https://github.com/glfw/glfw/issues/427 in GLFW (add missing diagonal resize mouse cursors).

Features

Viewport: The multi-viewport feature needs users/testers to move forward! (see #1542, available in docking branch`).
Viewport: In particular, Linux/OSX have issues and need some work from volunteers. See #2117.
Tables: Feedback wanted! See #2957.
Docking: Feedback wanted! See #2109.

Platform/Renderer Backends

Mac: imgui_impl_osx.mm need some love (#1873)
Mobile: Wanted imgui_impl_ios.cpp Platform Binding+Example for iOS (+ use existing renderer).
Web: Wanted imgui_impl_emscripten.cpp Platform Binding+Example for Emscripten (+ use existing renderer to create a new example). (#336)
Any of the third-party Unreal backend need multi-viewport support!
Any of the third-party Unity backend need multi-viewport support!

External Language Bindings

Many language bindings are not kept up to date (see https://github.com/ocornut/imgui/wiki/Links)
Considering switching bindings to use the dear_bindings or cimgui generated data so users of your framework/language can stay up to date without manual intervention.
