Thanks for the feedback!
Yeah I noticed it would be useful to cluster related packages together, that was the thinking behind introducing the filters to the right-hand side e.g. framework, test etc. When you click them it will toggle the view.
I was hoping I could rely on the keywords associated with the package to cluster them, though as it turns there's not a lot of love for the keywords section, meaning clustering them would take manual effort. Doing it myself isn't feasible and I though about creating the means for users to contribute the info, just wanted to wait for demand for it first :).
Thanks!
