The script editor has several view preferences that will apply only to your view of the script without affecting what your collaborators see. View preferences live on the status bar at the bottom of the script editor.
Pages and Pageless View
In pages view, you see your document as it would look printed on 8.5 x 11" paper. Margins for each block type are preserved, so if your browser window is narrow, you might have to scroll horizontally to see the entire script.
In pageless view, page breaks are hidden, margins are reduced, and lines of text wrap and unwrap to fit the space available. Pageless view uses space very efficiently, allowing you to see as much text as possible. It's especially useful if you've zoomed your document, or if you're in split editor view.
Zoom Levels
Zoom lets you zoom in to make the text in a script larger, or zoom out of to see more of the script at a reduced size. To change the zoom level when you are editing a script, click on the zoom menu in the bottom status bar and select a zoom %. To make the text look bigger, choose a number larger than 100%. To make the text smaller, choose a number smaller than 100%. You can also enter a custom zoom level if the preset options aren't what you want.
Once you pick a zoom level, it will be applied to any subsequent script that you open.

When you are writing in a script you can control whether or not you see:
Collaborator's avatars in the left margin of the documents
