What happened to the Finder window 'jellybean' in OS X Lion?

Solution 1:

The jellybean was removed completely in Lion. However, keystroke Opt-Cmd-T or menu option View - Show Toolbar will achieve the same thing.

I miss the jellybean too!

Solution 2:

Note that the lozenge or "jellybean" as you call it used to show and hide the toolbar. Pre-Lion, it did exactly the same thing as the cmd-opt-T keyboard shortcut, and this shortcut remains in effect in Lion.

Lion adds a new cmd-opt-S shortcut which toggles only the sidebar (which is in any event displayed only when the toolbar is already present).

Solution 3:

It was removed completely in Lion.

To eject disk images I normally just drag the icon in the window title to the trash. Quick and simple. You can also right click on the window background and eject it via the context menu.
