Came here to say this... but actually, when I think about it, I use it much less than I could/should. It gets confusing after a while: you can't find the lists you have, and start making the same list over and over again (in my case, things to pack when going out on a photo trip).

It would help to be able to attach metadata to items, and especially to have the app record the date of each item, and then be able to sort all items by date (regardless of depth, etc.)

workflowy.com is a great product. I wish there'd be more development on it though. It seems to me the product has become stale and the devs just sit back and collect revenue.
