Pane dividers now show that they can be dragged. The divider between panes carried only a faint marker, so many people never realised it could be moved to resize the panes. Each divider now shows a clearer handle: a thin line along the divider with a rounded grip at its centre, drawn in the standard raised Windows style and following your theme and high-contrast settings. As the pointer moves over a divider the grip follows it and the divider highlights, so it is obvious where to take hold and that the panes can be resized. The strip of record tabs in an inspector, which doubles as a handle for resizing the pane beneath it, gained the same cue: moving the pointer over its resize area shows the vertical resize cursor and highlights the strip.
