Inbox Categories? No thank you.
Hey Yahoo, I'm really disappointed at the recent inclusion of Inbox Categories - I avoid other mail servers specifically because of these. If you're really intent on implementing them, I'd like an opt-out setting where they don't appear in my inbox. This is not conducive to the way I use my inbox and represents an unwelcome change making my email noticeably harder on every visit, especially on mobile.
Have been very happy with your service for a long time, and am disappointed to see you just replicating your larger competitors.

We encourage you to read at the top of the Uservoice header (forum). There we provide What’s New, Coming Soon and some Tips. There we mention how to disable Inbox Categories: All, Priority, etc. Definitely read those as we update them with useful information. Thanks.
