HopHop, the iOS app formerly known as Ping that turns your inbox into an IM-like feed with the mission of making email more manageable and fun, is rolling out a notable update today. It ushers in support for the iPad and a unified inbox feed for multiple email accounts.

The unified inbox should be a welcome addition – Hop tells us that it’s been the most commonly requested feature from users. Additionally, you can now send photos and documents directly to Dropbox, Evernote and Twitter; browse all shared images and documents with a thumbnail preview, and swipe-and-hold to archive, trash or mark messages for later. There are also new customization options for the interface. The update should be available right now.
