Suffering From Label Overload? Help is Just a Click Away

"We created the 'Hide read labels' and 'Hide Labels from Subjects' labs to help people manage their ever-growing lists of labels. Given the popularity and usefulness of these labs, we've decided to graduate them into fully-fledged features."

It's always nice to see Lab features move on up to the big time. I use a similar feature extensively in Google Reader and can imagine that it would be helpful for hard-core Gmail label users. So, how many labels do you use and do you think this feature will be useful to you?
