The walkthrough tool almost works at 100% with the multi-pane view.
With multi-view panes enabled, and a floating view pane as the active view, I activate the walkthrough tool.
The keyboard hotkeys to move left, right, up and down work as designed, but the error comes when clicking the left-mouse to enable the camera to orbit.
At that time, the active cursor shifts to the Top Left view pane, until I click the left mouse button again. Then my floating view pane view is refreshed, and the active cursor is restored to the floating view pane window.
I have been able to use the walkthrough tool successfully in the multi-pane view, without a 'floating view pane'.
