Some explanation of how space between paragraphs currently works would also be helpful: sometimes I get a clear line space between paragraphs and sometimes none at all, and I cannot work out why this is, and thus how to change it. I am a graphic designer, so typographic control matters to me!

Add kerning to space letters that way we can put the cursive kernel letters on top of the printed text underneath and have bomb notes lol

Yes please do this!!

I second this. A simple leading/line-height option shouldn’t be terribly difficult. The textbox feature isn’t particularly useful without it!

This would be useful for when I want to use a text box to fill in a lined section of a PDF. Right now, it's a question of luck as to whether I can find a font size that lines up right.
