* Show declname in java import error * Don't clear window stack when saving preferences * Fixed spacing in source group UI, status view and error view * Resize graph scene rect when widget is resized * Graph node centering respect no animation preference * Fixed undoing of view commands * Avoid scrollbar jump when restoring graph scroll position * Deactivate local symbols in code when clicking into empty space
