Select the Pen tool to choose colors. You can dock up to four colors and customize them by selecting Spread and Settings, where you can also adjust line thickness.
Use Clean to erase all annotations, or place your palm on the screen to erase specific areas.
While using the Mark tool, navigation is disabled until you exit the annotation mode.
Although designed for temporary use, you can Save your work to the Android Finder app, Share it via a QR code, or select Cloud to upload it to a connected cloud drive.
