It appears that when I preview text file (.txt) saved on Drive in a web browser (latest Firefox), the content window (class="file-preview-text") is shrinked to something like possibly 800px instead of using full width of my window. This becomes an issue when the previewed file contains for example log lines or some code with long lines, since low width significantly decreases readability. There should be some button to switch view or a detection that this is a log file or a code and automatically use full-width.
