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 a sub-menu.
This patch adds toggle buttons for the two most commonly-used view modes (Short view and Detailed view) to the toolbar. Also moved the preview button over to the right so it doesn't compete with the new view mode buttons.
