Without this patch, changing the view mode is unnecesarily difficult: you need to click on the settings button in the corner (which has an inscrutable icon before arcpatch-D11993), then navigate to sub-menus if you want to change the view mode or sort order.
This patch adds toggle buttons for the two most commonly-used view modes (Short view and Detailed view) to the toolbar. and moves the preview button over to the right so it doesn't compete with the new view mode and sorting buttons.
