Andreas, sure, most things that are made into configurable options are “a matter of taste”. The problem arises when some peoples’ tastes are made available as options (such as yours, apparently), while others’ aren’t (such as mine in this case). The best thing would then of course be to make available options for both these tastes, which is exactly what I’m suggesting.
Adding line wrap indicators could possibly be a third taste, but from a purely objective viewpoint it’s at least not nearly as efficient a method to quickly determine the extent of the current wrapped line, since you then have to track with your eyes right and left several times for a multi-wrapped line, while a background coloring of the entire wrapped line is instantaneous and you don’t have to move your eye focus at all.
So please Mr Emura, couldn’t you consider adding a “part” for this as well?
