How to easily change "Browse By"

It used to be very easy to change the "Browse By" options in versions prior to OrangeCD Catalog v 6.1x as you could pull down a menu on the left hand side of the screen.

However, somewhere along the line, this all changed. Now there is only a box next to "Browse By" and I can't figure out how to consistenly change this easily. Specifically, I like to switch back and forth between sorting my collection by "Artist (no compilations)" and "Date Added".

Can someone tell me how to quickly and easily do this now?

It sounds like all your dropdown presets have gone mising, If you right-click anywhere in the content tree a pop-up box will appear. If you select "Customise View...", and then select the "Drop-down presets" tab you should be able to check what presets you got, and modify them as you wish.
