LINE SPACING is virtual impossible to deal with
I like to add FOOTNOTES to my emails I create. But your FONT sizes do not change LINE SPACING. If I use 'tiny' font, the font is TINY but the LINE spacing for the next line is HUGE and there is NO LINE SPACING CONTROL. Same if I copy text from Microsoft WORD with single spacing, to Yahoo Mail, it DOUBLE OR TRIPLE SPACING AND NO WAY TO CONTROL IT. This has existed since YAHOO EMAIL was created in 1997 as I created my account in 1998.
