Some of these interfaces might be really fun to implement, but there are very few of them that I think I'd want to use. For me, writing code is about the easiest thing I do. Other than identifier completion, I don't need much beyond a basic text editor. On the other hand, understanding code -- not just exploring it, but understanding it -- is the the hardest thing I have to do, and that's where a good UI could be helpful. I only made a superficial scan, but it didn't really seem like any of these UIs were designed to do that. I don't really need a map to a code base so much as I need a tool for making my own maps (not just one!) into the codebase as I try to understand it. Or understand at least enough of it to do my current task.
