I think the problem in such situations is that the M needs to address two different use cases: 1. Reference for what exists. This is used by people who don't know what %Ð is a placeholder for. Alphabetic sorting has a big advantage here. 2. Manual for what can be done. This should arguably be grouped differently, e.g. Full dates, years, months, days, etc. since there are often several placeholders for each category that are otherwise pretty far apart at times.
