Gmail address book gets needed improvement

If you've ever tried to add someone to the address book of gmail then you know how frustrating that is - or, rather, WAS. They've made a HUGE improvement to it that I just now experienced.

I went to change an address but was told that I could do it because it already existed. ARGH! But this time it showed both entries AND a link that allowed me to merge them. WOOHOO!! With one click it showed me both addresses, each with a remove button next to it that allowed me to remove the one with the old address. Two clicks was all it took to get this issue resolved. Very nice.
