Helper dialogs like the Tool Settings or the Color List are "dockable" in PhotoLine. "Dockable" means, that the dialog can be attached to another dockable dialog. This way the user interface is more cleaned up.
Furthermore on Windows dockable dialogs can be attached to the edges of the main window. By doing so they will automatically adjust to size changes of the main window.
On Mac OS dockable dialogs can be docked to the edges of the screen.
If you have docked dialogs to an edge, document windows will not be placed behind those dialogs.
If a dialog should be placed at an edge without docking, you can do so by holding the Ctrl-key (Windows) or the Command-key (Mac OS) while dragging.
Different configurations of the dockable dialogs can be saved as dialog settings (see chapter 7.3.1 and chapter 7.3.2).
Dockable dialogs can have a helper menu with useful commands. This is indicated by a small triangle in the upper-right corner and is called the window menu. On OS X you can use this menu change the orientation of the dialog between horizontal (titlebar is at the left edge) and vertical (titlebar is at the top).
