On our beta survey we ask for the ONE feature users wish for, if any. Here is another great example of how sometimes you can miss a thing. A participant in this survey wrote “A second window (viewport) to the file similar to Excel.”
Now, I don’t really remember when we started having that, I think it was somewhere around version 2.0. But the feature is so subtle, unless you know about you may miss it.
Consider a very long script with many, many declarations on top.
And here you are, looking at the top of your file for reference while editing on the far bottom of it.
