Useful program indeed. Would be perfect if one could start with a whole list (e.g. of groceries, all the groceries he/she is used to buy for household) with everything unchecked. Then decide what to buy today and check those items; checked items go upfront in the list (contrary to present when they slip down in the list); and when shopping, you uncheck all the things you get so thet the upfront list of things to buy gets thinner and thinner. In other words, the opposite behaviour than now ;)

@Ernesto de Bernardis,
Thank you for your feedback. I'm happy you find the app useful. I hope it will serve you well. As for your request, I can totally see the benefit of it. However the functionality is very different from what EasyList is now. I won't implement your idea, but perhaps someone else might pick it up and create a list based on your idea. The more variety in apps we have the merrier.
