I’m not sure what this return icon is for, not even sure if it’s intentional or not, perhaps there’s
functionality I’m not aware of? I noticed it only shows if you typing above a line of text but not if there’s an empty line below.
If intentional and it’s supposed to do or mean something, from a dummy user perspective perhaps when you hover over it for some time a small help tooltip should pop up to say what it does and what the user should do e.g. display a keyboard shortcut?
yes, this is something quite obscure of the cmark syntax. If you want to separate paragraphs in markdown you need a blank line inbetween them OR you can add 2 spaces after the top line last character. The symbol is there to show there’s separation between the paragraphs. A tooltip might be an idea. I guess the hard part is coming with a meaningful and short sentence.
