Make searching libraries for selected programming languages implementing certain algorithms or datastructures easier, and provide some filtering by tags or even some code quality metrics. Sorry for overly broad answer, but the current functionality almost provides this, but it is not still quite working when you really want to find a good interval tree or balanced binary tree implementation for Python for example. Use of Cython or C library bindings could be filtering options for example. To generalise, it would be good to be able to find a performant or extendable library, or both. Also very important thing is that the library is maintained, has more than one contributor etc.
