First a pat on the back:
You guys really seem to have gotten one of the major uses for a mobile app of this type: collecting information. Photo notes and voice notes are really a good extra.
But there’s one aspect that isn’t as well represented. Most of us on the go need to be able to easily manipulate checklists. Shopping lists, a simple on the go list of tasks, things like that. As it is in order to check off an item I need to click on the item, flag (or un-flag) it, and hit “Back”. A three step process. I’d like to see the flag attribute more accessible from the list to make this a one click process. Even making it a context menu item would make it a two click process without taking focus away from the entire list.
It sounds trivial but if you are checking off a dozen shopping list items, it becomes more than a little inconvenient.
