As only a cursory user of said tools (but strong opinions) I felt the immediate desire to get an editable (2D) scene that I could rearrange. For example I often have a specific vantage point or composition in mind, which is fine to start from, but to tweak it and the elements, I'd like to edit it afterwards. To foray into 3D, I'd be wanting to rearrange the characters and direct them, as well as change the vantage point. Can it do that yet?
