Hi, i'm sorry for the delay in replying. I have not received the notification of your post...
This feature will be included as a new option in the Camera parameters of Forest.
We have planned to release a stable version of Forest in the next days, to complete the current beta phase of 3.5.x. Next, we will start to work on a new beta series, adding this and other features probably for the first version. At this moment i cannot give you a more precise estimation.
We usually don't add new features to the versions that are ready to final, because all changes in the code always introduces certain degree of instability.
