Don't "rubberband" the activated thought in expanded view
It's a needless distraction. I tend to edit notes on several children of a parent, while keeping them all in view. Mouse-over editing of children works in normal view until the user moves the mouse cursor over the note. Expanded view is better for the task, because it enables the user to to activate a thought without recentering around it.
But I'd like a "quiet" toggle...there's no reason to spring the view if it's only going to retract right to where it was. Sometimes a long Thought title is truncated until activated, at which point it covers its neighbor, even after the redraw. There would be some reason to redraw if activation cleared some space around the Thought , but it actually doesn't. So this seems like animation for its own sake, which impedes quick editing. Please let the user turn it off.
