A few points - initial play;
When the node column is dragged to the right (by dragging the button) the View menu option Show Palette is unticked (as it should be) but it can still be ticked - to show an empty column. It would be better if it was disabled when the nodes column is on the right.
Access to the Configuration nodes is shown in the menu, I think this is overkill as it is also available in the View menu option and in the right-hand tab bar.
Love the Toggle navigator, makes it much quicker to get to the bottom of a long flow.
Zoom to fit, would it be possible to have an Un-zoom so that I can toggle it on & off?
Just being picky now, but would it be possible to have a 2 overlay on the Dashboard 2 icon (I know the tooltip identifies it but..)?
Not sure if it did it before 4.1.2 but still does it, when zooming in, then out, the view point moves
