Is there any way to change line&paragraph spacing? Reading a very long thread without enough space among lines is somewhat confusing and hard.

Of course one can tab Enter twice to simulate line space value of 2.0 (like in Microsoft Word 2016)

However, as the window-size of a thread changes, Text editor automatically wrap texts, so it is sometimes hard to predict.

And among all of the options of the text editor, I failed to find anything related to line spacing. Only paragraph style of "spaced"

Just like this line. But this one is related to horizontal space.
