I'd love to see OmniFocus automatically sync with iCal on app launch and app quit when syncing is enabled. (Actually, I'd love to see live syncing with iCal, but I'd be happy with on app launch and quit.)
Anxiety makes a perfect lightweight way to work out of OmniFocus while resisting the temptation of "fiddling". The only thing that slows down working in that manner is having to remember to sync with OmniFocus whenever I actually
do have to drop into planning mode.
