The new iCal and Address Book in Lion are too dumbed-down for me to use and don't fit with my work-flow anymore. Can anyone suggest a good iCal and Address Book replacement? I use my computer for work and need to be able to juggle 20+ calendars and address book groups. It would be nice to have a calendar app that has the old 10.5 iCal style/layout with the left and right sidebars to select calendars and also edit events without them obscuring the actual calendar. Also, I need the little month calendar in the bottom. For the Address Book I need to be able to see my groups, list of contacts and individual contacts at the same time. Why Apple decided that our quad-core computers can only handle displaying two columns of information at a time is beyond me. Thanks for any suggestions.
