I too came across the problem of putting checklists into the Toodledo format, especially for packing for work trips. Problem being that once you check the box the item disappears, whereas I want to repeat it next time around.I went back to my own (simple) design in Excel. Just a list of items and a cell next to it where I can put a Tick. The list can be modified for a particular occasion by putting X next to items i won't need this time.
Any suggestions for a way of doing this in Toodledo, or other apps that can sync across to iPhone etc?
