Linea Sketch

Linea Sketch was updated to version 4.0 this week with lockable layers, a new set of watercolor brushes, and the ability to annotate your artwork with labels, something that collaborators should find useful. Annotations support both the keyboard and Scribble with the Apple Pencil and support adjusting their color, size, font, and rotation. Merging text into an image layer opens up options to add effects. The watercolor brushes come in three sizes with three effects: Simple, Wet, and Cloud. Annotations and brushes are both premium features.

Annotations are a new version 4.0 feature available to everyone. Tap the lock icon in the layer palette to toggle the lock on, preventing edits to a layer. It’s the sort of feature that is standard in more complex drawing tools and a nice addition to Linea.
