MacOS – alfUIplugin.plugin

Phew! I decided to do more digging on my own.

I took a look at a computer still using Snow Leopard and right-clicked on its "Today" folder to reveal its path: /System/Library/CoreServices/Finder.app/Contents/Resources/CannedSearches

It turns out this directory still exists in Lion!

So go to Finder, and use the Go To Folder command (cmd-shift-g), and enter that path above. The "canned searches" are all still there. Drag and drop them to your sidebar.

Nirvana.

It's the kernel extension for JMicron SATA controllers, and yes it's official, as are the others. It's up to you if you want to delete them, I wouldn't bother as they take up minimal space. Check System Profiler before doing anything silly just to make sure your iMac doesn't require any of the listed extensions.
