The more code one can see the less scrolling and the easier it is to find bugs. The page layout and text editor could be configured to got from top margin to bottom if the browser window permits.

That would be a huge UX improvement for debugging.

We have just released MARIE.js v2.0 which has a tiling window interface, which makes it much easier to view code and see results in other windows.
