Oh and here's two other things: add something for camera rotation (better yet - make a camera behavior), and for some reason the game freezes during loading if i set unit res to 1.

The way you manipulate cameras is via events mainly by setting camera position and camera target. Some actual rotation actions are still missing though as you noticed.
Edit: rotation actions and camera behavior were added in the latest update.
Unit resolution of 1 is probably a bad idea as you most likely wouldn't want a single pixel representing a unit in the 3D world. Didn't freeze for me when I quickly tested with the example project though.
