The subject says it all.
I have an old GMail account which has almost 800 contacts stashed away. Almost none of that was my doing, it's GMail being smart for me. I appreciate that, but I wanted to purge the list. Since there's no feature to just do that, I needed to view the list, select all and delete.
But I can't.
The functionality is there. Visiting the contact list is hard, and I sometimes hang right there, but my computer always strains when I'm actually trying to select some/all and delete contacts. I once deleted a handful and then it hung afterwards.
I bet it works just fine with Chromium.
