  • Collapsible sections with optional enable checkboxes
  • Toggles with inline color and slider options, color pickers, sliders, radios, and combos
  • Key binding with a searchable key list

• Settings & profiles

  • Declarative typed settings groups saved to INI
  • Named profiles saved as .volk files with a built-in profile picker
  • Per-app config and asset folders under C:\Volk

Building

VolkDMAOverlay builds as a static library. It requires Visual Studio with the v145 toolset (C++23) and vcpkg with Dear ImGui installed for the x64-windows-static triplet, including the DX11 and Win32 backends:

vcpkg install imgui[dx11-binding,win32-binding]:x64-windows-static

Clone with submodules to pull in VolkLog:
