Why is the editing window so small?

So I'd like to bring up the issue of the editing window in Twine 2.
It's too small and I can't find any way to make it wider. Maybe it's just me being an idiot, maybe it's the program choosing aesthetics over ease of use in one of the most crippling ways I have ever seen.

There's enough room for exactly 63 characters in a single line. When dealing with anything more than a single nested statement, that is simply not enough space. Heck, I have individual for loops where the condition is so long it pushes the $i++>> down to the next line, no nesting at all.
Why can't we make the editing window wider? Why does it wrap at a mere 63 characters? Even Microsoft Notepad allows for 1024 characters in a single line.

I feel like allowing the editing window to be resized and increasing the wrap limit to a friendlier number, like at least 256, would greatly improve Twine's user interface and make code much easier to work with.

A small sample of my code pictured here:

Notice the number of times the line reaches the end and has to wrap to the next line.
