Description
Different use cases like programming or writing commit messages have different requirements on line breaks which users might want to do manually.
The creation of text in such use cases could be supported by vertical lines in different colors, e.g. one at 50 characters for the ideal summary length of git commit message for GNOME and 72 characters for the recommended max. line length of commit messages. The character offset and color could be configurable for each profile.
