... that the Patcher pane's view can be zoomed in and out? On Mac, anyway. I just discovered this by accident.
I use an Apple Magic Mouse, whose top surface picks up movements of one's finger to control scrolling (and zooming.) If I have the cursor in the Patcher pane and hold down the Command button, moving my finger on the mouse (or, I suppose, on a laptop's trackpad) zooms the view in and out across a very large scale - 50 times? And the graphics and text remain razor-shaper no matter how close you get!
Who knows, this might be useful for extra-large setups.
