We love writing. That's why we're here. Literature & Latte was born out of a desire for tools that embrace the creativity of all forms of composition. We make software we love to use—Scrivener, hugely popular among authors of all stripes, and Scapple, crafted for freeform note-taking.
To adjust page margins and other print settings, go to File > Page Setup... and choose "Scrivener" from the top pop-up button.
