Is there a video which showcases the unique aspects of RA2 gameplay with Phobos?

Scroll through the extension docs:

https://phobos.readthedocs.io/en/latest/New-or-Enhanced-Logi...

They have recordings of most of the different features Phobos enables.

Hopefully there will be in future. But for now the docs do have fancy GIF illustrations of Phobos features used, which is the closest you can get.
