The left panel: the sidebar
The sidebar consists of the panel of tools available along the left edge of your screen. It has two sliders, one square-shaped icon, and two curved arrow icons, as shown here:

Let’s see what these controls are used for.
Brush size slider
The first slider is used to change the size of the brush/eraser/smudge tool that you are using. You can tap anywhere on the slider to jump to a brush size or manually slide it up and down.
Figure 3.9: Size slider
Procreate also allows you to save specific brush sizes that you frequently use. This feature is called Brush Size Memory, and it’s discussed in Chapter 8, Painting Tools and the Brush Library – Using and Organizing Brushes.
Brush opacity slider
The second slider works in the same way but for brush opacity, which is how solid or transparent each stroke will be.
