As mentioned, here's an updated version for everyone's downloading pleasure:

<font color="green">(ADD)</font> Transitions. Specifically, movement and zoom transitions. Cameras can be set to transition from one position/zoom level over a specified period of time. There are conditions to check when a transition ends or is in progress and expressions to get the progress of specific transitions.
<font color="green">(ADD)</font> Actions to set basic properties of cameras such as position, X, Y, and zoom level.
<font color="green">(ADD)</font> Action to switch between cameras - I'm not sure why this wasn't there already.
<font color="red">(BREAKING CHANGE)</font> Object following is no longer enabled by default -- there is now an action to explicitly enable it. The reason for this is the camera transitions - movement transitions disable object following and "zoom to contain" upon starting -- zoom transitions only disable "zoom to contain". These must be re-enabled manually upon the transition finishing.
<font color="blue">(CHANGE)</font> All cameras are updated every frame now, regardless of their status as the currently active camera.
<font color="blue">(CHANGE)</font> "Set scroll smoothing" action has been hidden. This feature is not yet completely, so I have made it inaccessible - if it's in your project for some reason, it will remain there.
There may have been other small changes that I can't remember off the top of my head, so go ahead and poke around, try to break it, and let me know what you find.
