21 -* Collections re-implementation supporting Java Generics. This means that you may create an NSArray, NSDictionary or any other "NS collection" typed to a class or interface. I don't actually like this feature, because I'm a LISP lover and I see this as unnecessary constraints. Anyway, I mention this because I admit it may improve the code quality in some ways, and because WONDER implementation is, in some ways, better than Apple's (Apple delivered generics support for collections in 5.4).
21 +* collections with attachements

23 -* COUNT SQL query generation. This is a very, very useful feature, at least for me. There are many times when you just want to know how many objects are selected by a query, but you don't want the objects themselves, specially because we may be talking about tens of thousands, or more. Think something like Amazon querying its system for the number of books sold this month. The query results would be huge and unpractical to manage in memory and time, and an unacceptable overhead if all you want is the count. WONDER provides a very easy way to do COUNT (and COUNT UNIQUE) queries.
23 +* count and count unique

25 -* Extra qualifiers. Sometimes WO qualifiers are simply not enough. WONDER provides some handy qualifiers. Some of them are buggy and may not work, it's not one of the best quality WONDER features, but at least it's there, and it's open source, so you can fix any bugs you find.
25 +* qualifiers
