Change various preference settings.
The Lagoon tab of the Preferences contains options for changing not only the lagoon, but also marking menus has been added. Create your own marking menus, populate the lagoon with the options you use most frequently. If you never use a tool, take it out and replace it with one you do. This tab gives you complete control over these domains.
In addition to all this, now when you’re working, you can right-click to access a virtual floating lagoon. It uses the setting from the Lagoon Preferences. These setting are saved to an .xml file, so you can save them to a portable hard drive, take them with you to use on any machine, and always have your custom setup.

Customizing lagoon icons
You can also customize the marking menu for an icon in the lagoon, adding tools that you commonly use. Once done, you can use clutch keys or right-click to access these custom marking menus without visiting the lagoon.
In the Lagoon Preferences, at the bottom of the Default SketchBook Tools list, any Do-It-Yourself brushes you have made will be listed. Now, you can add them to any custom marking menu.
