First up: the Dock Menu option. Simply check this in the Get Info window (cmd-i) of any folder in Camino's bookmark manager and enjoy easy access to your 'marks from the comfort of a right-click.
Next is that Tab group: this is useful for creating a set of bookmarks that all open in their own tabs at a mere single click of your mouse. Do you consistently open webmail, Amazon and - of course - TUAW when you sit down for a stroll through the web? Camino's Tab group just might save you hours of clicking... after using this feature for, like, 20 years.
