To dock the reference browser to the left, click the ◀️ Move to left button on the top left of the reference browser.
This will divide the app into two resizable halves. The viewport and the workspace shrink or expand as you resize the reference browser.
To dock the reference browser to the right, click the ▶️ Move to right button.
This will dock the browser into the right half of the app.
Docking the browser to the right behaves differently from moving it to the left. When it's docked to the left, resizing the browser shrinks or expands the workspace with the browser. When docked to the right, the workspace remains as-is, and the browser is not resizable. Additionally, you cannot interact with the workspace while the browser is docked to the right.
To have the reference browser take up all the available space in the app, click the Move to full icon.
To move the reference browser to the default center position, click the 🔽 Move to center icon.
