Gordon,

"I'm not disagreeing with that, though I would caution about how much adjustment is sensible. It's fine for someone very familiar with a tool, but how, for example, would one guide a newcomer to a particular feature or button when it could be nearly anywhere in a large, complex, configurable interface. Writing a manual would also be challenging."

You can have 2-3 common templates: Easy-Intermediate-Advanced and have them as a default views. You don't want to customize - use given. I am certain most of those who would want to customize, would have certain experience or desire to explore. One of the most cited problems with BIAB is complexity. That is mainly because all the poorly designed menus are "in your face". Good, flexible design will alleviate that.
