That's an entirely different issue. I think what you're talking about is just a shortcut for typing quickly. Even then a double space is replaced with a period and single space.
~~I'm talking about two paragraphs with two linefeeds in between will be displayed as a single paragraph unless there are two spaces before the linefeeds.~~
I kind of understand what you're saying. But in an age of smartphones, I have to manually add double spaces at the end of every line for the end product to display as it appears when editing it. This probably seems trivial and stupid for folks on desktop, but even Discord has this figured out. Is this something that needs to be added at the app level?
Yeah, had a brain fart. I mean your second case. This seems trivial when typing short comments as you've done, but it's incredible tedious when copying and pasting long lists and articles.
