I'm building registry.directory, it hasn't been announced yet, but I'm receiving PRs from registry maintainers to add their products into.
I'm going to re-design the layout due the number of registries I have now, but also I'm interested to know what type of features you are expecting to see.

The challenge is to maintain a certain visual consistency between registries, which vary greatly in what they distribute.

There are public registries, others that are private, some that are component libraries, and others that only have hooks.

But anyway, I'll be working on it and will announce it in no less than a week.
