Guardln/ImGui-External-Base — reverse-engineered prompt

Build me a simple Windows C plus plus ImGui external menu starter project that I can open in Visual Studio and run right away.

I want it to look clean, with a dark styled menu, a custom font, and small icons so it feels more polished than the default ImGui example. Make the menu easy to edit, with a few example sections and controls so I can later add my own options without fighting the code.

Also include a small set of basic helper functions for input actions, like moving the mouse, clicking the mouse, and pressing keys. Keep them simple and separated so I can reuse them.

Please keep the project lightweight and beginner friendly. Add clear comments where someone would change the menu style, add new buttons, or use the input helpers. Don’t overcomplicate it with extra systems. If you need to check the latest ImGui or Windows API details, look them up online.
