I have installed and checked the addon and "saved preferences… But it does not show up in the main Layout window. I do not get the icon in the T panel as shown in the video. Nor do I get anything in the preferences window (in the addon window) all I get is the button for “Documentation” and the one to the right of that for “Remove.”
I type Alt+W and nothing happens.
What am I not doing? Thanks for any help.
