Show HN: Osdialog – A cross platform wrapper for native dialog boxes

I wrote this library for developers of video games and cross platform applications to use native operating system dialog boxes using a simple consistent API. It's a work-in-progress, but most useful features work.

I'm also posting this as a call for help. I'm not an expert at all three platforms, so if you're familiar with one of the platforms and happen to see any issues with the code (e.g. memory leaks on MacOS), send a PR! I'm also happy to take requests for more types of dialogs that all platforms support, like font selection or print dialog.
