What's the Navigator and how do I use it to save memory?

Wavebox's unique Navigator lets you view all your apps & tabs by memory consumption.

Unique to Wavebox is the Navigator. A visual map of all your running web apps, tabs and windows.

To launch the Navigator click on the 'Compass' icon in the title bar (top-right), or in the sidebar (bottom-left)
The thumbnails can be arranged using the icons top-left by group (uneven block icon), app group (even block icon) or CPU consumption (speedometer icon) with the largest using the most memory.
Move your mouse over the title bar of any app/tab/window to see how much memory it's using.
You can close tabs and windows by clicking on the X icons.
You can sleep apps by clicking on the 'moon' icons.
To keep the Navigator open, click on the 'pin' icon top-right.
To display everything in Wavebox, including sleeping apps and tabs, click on the 'moon' icon (top-left beneath the zoom in and out icons)
