I'd be happy to add an "explore button" to CPANdeps, if someone else tells me how, and promises to maintain it. I'd also welcome any help that anyone can give me with the design.
CPANdeps, like most other things in the perl community, was originally written because I had an itch that needed scratching. I stopped when it worked, but since then have added features and made some minor tweaks when people suggested them. If someone who knows how to write HTML has any suggestions (preferably in the form of a patch that I can apply to the publicly available templates) then I'd be delighted to apply it. The only constraints I'll impose on any contributed design are that functionality, compactness, and ease of use are more important than prettiness.
