HeaderView is a small extension for C/C++ devs who need to keep their header files close by.
You can chose whether or not existing header files are moved to the right side of the screen with the corresponding flag in the extension settings
HeaderView does not track any data from the user apart from the data already taken directly by VS Code. The full code is available on Github.
If you encounter any issue with this extension, please open an issue on the Github repository and I will try to fix it as soon as possible.
