This first note in this thread states that Anchor notes is "impossible". First, are you kidding, anything is possible. Second, you should hire people who know this. Third, if this many people want this feature and your (Evernote) think it's impossible the correct approach is to assign the task of a whitepaper on why its impossible (Specifically). If by the end of the paper that person can't give you a solution you have the wrong person. But if the solution is complex or abstract give the problem to a real programmer or 2. You will get solutions. Review that for consistency with your implementation philosophy, see where it breaks, fix that, add the feature, and move on.
