Wow! So you are thinking bigger than I had imagined. The fourth monitor is exactly as you say, a remote full project view. Are you thinking in terms of projects and clips? A project can be just one piece of animation or made of several scenes that make a project. There’s lots of features to come up with but that begins to make the software very complex and my impression was that you want to avoid that. I think you are right on to make a software for beginning animators. BTW I like your layout style which promises to keep things simple. If you want to we can Skype and talk about this. My website is slocumfilm.com and my wife, Sandra and I have lots of stuff on Vimeo.
