A month after shuttering Google Wave, the company has announced that it will be fleshing out the Google Wave code to turn the current example Web server and client into a complete application called Wave in a Box. Although Wave in a Box won't have the full functionality of Google Wave, it will be made available as open source, and Google's hope is that a vibrant developer community will help Wave move forward and fulfill its initial promise. We're not holding our collective breath, but it could happen.

One of Gmail's most ballyhooed features is its excellent spam filter. But having reduced spam annoyance to a dull roar, Google has moved on to another troubling inbox management issue: even "legitimate" e-mail contains plenty of both wheat and chaff. Google's latest Gmail feature, dubbed Priority Inbox, aims to make inbox management a bit easier. Through its own analysis and your manual training (much like you would train a spam filter), Priority Inbox learns which messages are more likely to require immediate attention, and which can wait. The feature splits your Inbox into "important and unread" messages, "starred" messages, and "everything else." Google says it will roll out the new option to users of Gmail and Google Apps alike over the coming days. We'll see how it works when it appears in our accounts.
