Apologies for not reporting back sooner, but still
No transparency effects enabled anywhere in OB, and the folders still don't work. Adding the icon to a folder manually works, but there's no way I'm adding over a hundred icons to my setup manually, plus it'll loose my auto sync with the Windows start menu (I've setup a couple of custom batch files to sync in icons created by installers when the PC boots)
Tray area- You're right, apologies

Sometimes I forget just how much I've customised this machine. Basically, custom widgets & similar are working, but it's not cloning the Windows tray in.
