Appearance
Choose Dark or Light when you want a fixed workspace appearance. The app also follows the system appearance on a fresh launch, so it feels at home on iPad and Mac.
Preview controls
Use pinch or the preview controls to inspect an equation from 1x to 4x. Zoom changes how you inspect the equation, not the source or the exported result.
Output controls
Set the export font size, PNG quality, and text color from the export rail. These options are deliberately separate from the source so you can reuse one equation for several destinations.
