Layer Panel
The content of the Tool tab in the sidebar and the tool settings above the 3D view is usually equal. The Layer panel is a special panel in this regards. It just exists in the tool settings above the 3Dview. And it exists in all grease pencil modes but the object mode.
Grease Pencil objects each have a list of 2D layers for grouping and arranging strokes in a List view. Any stroke can only belong to a single 2D layer. There is always only one active layer in the list (the selected one). When you draw, the new strokes are added to the active layer. By default the view order of the layers in the viewport is top to bottom.
Every layer correspond to a channel in the Dope Sheet editor (in Grease Pencil mode). Layers can also be used together with Modifiers to only affects part of your drawing.
The content is the same than in the Properties editor in the Object Data Properties for a grease pencil object.
