On a phone
On a small screen the background fills the screen and the controls sit in one bar at the bottom:
- Layers opens the layer list as a sheet. Tap it again, or tap the background, to close it.
- Edit opens the inspector for the selected layer, with the same Layer and Document tabs as on a computer.
- Play plays and pauses.
- Presets opens the preset gallery.
Parameter fields work by dragging sideways, so the sheet still scrolls when you swipe up and down. Tap a field to type a value.
Saving downloads the file, and the share link button in the top bar is the easiest way to move a background to your computer.
