If you go through a word processor that uses formatted text, and paste it there (like MS Word). Then set the font to "Courier New", line/paragraph spacing to 0, and then copy it into Lynch.
It seems like Lynch removes the extra spaces when the copied text is plain text, but if the copied text is formatted, it keeps everything as the original.
In this case, you have the alternative to make it as a table in Word, and copy the entire table. This will work since Lynch will support table display with all formatting. This way, you can have a nice font as well (no need for mono-space font).
