I just noticed today that the checkbox or "To-Do Button" to create to-do list was recently moved from the visible ribbon to the "Insert" drop-down. I'm not sure why this was, but it was extremely helpful to have it as one of the readily accessible buttons. I'm aware that the "Checklist" button is still there as a listing item, but these cross off text when selected, unlike the To-Do Button. I use this constantly, almost in every note I create. I know this is minor, but it worked excellent the way it was. Is this a permanent change?
The instructions haven't been updated yet either: https://help.evernote.com/hc/en-us/articles/209005597
