Improve Legibility of Section Breaks

It would be very helpful if the section break bar had a little more weight to it.

I’m using it in status updates as well as in task descriptions to help delineate sections of information, but the bar is so thin and faint that it might as well not be there. This would be particularly helpful in task descriptions where I am trying to provide both directions for handling the task itself as well as scripted information for the assignee to copy/paste out to another system. As it currently appears, a section break is almost no different than a hard return, and is essentially invisible.
