Well... Fiddled around with this addon for an hour or so tonight. There's a reason it says "BETA" in big, bold letters on the front page of the addon. It's buggy as hell. Several cases of camera stuck in a funky position or constantly spinning around in circles. For me, it's just too broken to be useful yet.

Second thing I notice is that it's not exactly easy to revert camera settings back to defaults. I had to reinstall the addon, reset it's profile to default, then disable each setting individually before I could uninstall it and actually not have vestigial remnants of the thing screwing with my views.

So, YMMV. The times when it did work leads me to believe it has some pretty nifty potential.
