Re: double side with tabs option
You can probably script something to automate the process. One of Rhino's strongest features is the ability to customize it to suit your needs. We run around 230 custom commands that make our processes much more efficient. Basically, anything repetitious and monotonous becomes a candidate for a Python script. In other cases, we can do things that Rhino can't do out of the box. I would have to think a tool to create tabs wouldn't be that unrealistic.
If I wasn't so busy I would take a stab at it, but right now I can't find the time. Maybe this winter we will slow down and I'll give it a go.
