[feature request] View file before saving #39

It's nice that I can export a file from Unity with the native file browser. However it would be even greater if I could view the file before saving. Instead of choosing where to save, it would say "open with", and then I choose the app to see the file, then I save. It's currently a little bit cumbersome, because I need to save first, the file browser closes, then I need to navigate on the file browser to find the file, open it, and see what I got.
