I'm curious about 2. I just downloaded and the first thing I noticed was how hard it is to use the save one handed. When I create a new task, I have only a single button in the top LEFT, which is the save icon. I can't reach that even with my giant hands on a OnePlus 8 Pro. I have no idea what the "checked" button is people are referring to, I even turned on the "hide" option for it and saw no change. In editing an existing list I see Save on the left, and 3 dot menu with Discard and Delete.
