You can use the Docking pane, located to the right of the Layout Area, to dock the following palettes:
Click the Expand/Collapse button on the vertical splitter bar.
If you remove all the palettes from the Docking pane and close them, you will not be able to see the vertical splitter bar and the Docking pane will be hidden. To reopen the Docking pane, open one of the palettes, such as the Canvas Assistant, and drag it to the Docking pane.
When you dock a palette, a tab with the palette’s name appears in the Docking pane stacked with the Canvas Assistant. The tabs of docked palettes give you quick access to tools or features and leave more screen space for working on your document.
Do one of the following:
Click on the palette name at the top of the Docking pane and drag the palette away from the pane.
Click the palette's tab to bring the palette forward.
Click and drag a palette's tab to move it to another position in the Docking pane.
Palettes that are docked in the Docking pane when you quit Canvas X Draw will be docked the next time you launch Canvas X Draw.
