I’m not quite happy with that change.
I was about to go on a mini-rant about how Markdown enforces readability of the source by allowing hard-breaks to not change the output, but it’s an already long-standing debate.
I will just say that I like to control what is a line and what is not, independently from the width of my editor window and its soft-wrapping. Consequently I actually never want to go to the end or start of a soft-wrap, because it does not mean anything to me.
I want to be able to go to the true home/end of a line, often to add a new line after or before it with the same indentation.
Most text editors implement this by going to the true line start/end by pressing “home” or “end” when already on the start/end of the wrap.
