Tag Suggestion

It's getting harder to organize my tagging system. There's already a cloud for most used tags, and the list on the side also shows it by usage. Is it possible to implement something so we could also view the tag list alphabetically?

Could you borrow the alltags page from flickr and also their organiser and adapt them for listal? Something like the flickr organiser would be really cool :) (though I suspect would take a lot of programming time)
