Hi Danny, this is set up for the next beta.

You'll be able to use a keyboard shorcut with this script:

script:moi.view.setCPlane( moi.ui.mainWindow.viewpanel.getViewport('3D').targetFrame );

Which when triggered will set the construction plane to align with the view orientation of the 3D view.

This won't work in the current Apr-12 beta though, it will be working in the next one.
