When you view a .txt file in a ProtonDrive (meaning when for example someone access it via public sharing link), it is better readable if the lines are not too wide (as it is currently), but when the .txt file contains for example a code or a log entries, then the too narrow viewer makes the file very hard to read, so you end up sharing such files using different service than Proton (which is bad).

I think that the width should be adjustable and by default made wider to fit/fill whole window. I am using Firefox browser.
