I found that in version 1.14.0-812 (I do not know if even in the previous) using the new editor, when writing an email insert RETURN, the cursor
it does not appear in the line immediately below, but in the following line, for example:
abcder
efghil
mnopqtes
instead using the classic editor you get a correct writing like this:
abcder
efghil
mnopqtes
Thanks !
