- misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL)
- misc: provide HoveredTime and ActivatedTime to ease the creation of animations.
- misc: fix for compilation settings where stdcall isn't the default (e.g. vectorcall) (#1230)
- misc: detect user not calling Render() and suggest to call EndFrame()?
- remote: make a system like RemoteImGui first-class citizen/project (#75)
- demo: add vertical separator demo
