Hi!
First of all, thanks for the upgraded/extended ToDo list. We waited it, and we’re happy about that.
But… My wife just complained about the tick/untick. In the old version, if you make an item completed (ticked) or just removed the checkmark (so the item went back to the top) the UI remained in the original state, but now, it’s follow the item. Maybe there are use cases where this came handy, but if you have long list, and have multiple items, you need to scroll a lot, which is not the best, when you just collecting things in the shop.
If there is a way, to let the user decide which behaviour works for them, i would be thrilled
