Great idea! I should be able to implement this.
Due to Unity limitations with the input event handler (or maybe my lack of skills hehe) its seems impossible to have both interactions running simultaneously (they kinda eliminate eachother), but switching between interaction modes depending of hand/controller should definately work! This will be high on the to-do list.
Just need to finish up the new manual importer with file browser that should be done and added in a new version by tomorrow afternoon!
