I frequently use line_objects like a ruler to line up my objects - the grid_view does the same job, but then the lines are not exactly where I need them, so I'd rather have my own.
<=> My problem with those is that they are quite broad - left and right of a vertical line, the object goes on, making it quite hard to leave the line in place and then move the object_to_be_aligned.
You could always just stretch out a text object instead of using a line object that way you don't need to deal with the excess space around the line objects.
