Yahoo is testing a new version of its web-based email service featuring a new interface more like that of a desktop e-mail application and faster response time.

E-mail caching; message preview; drag-and-drop filing; the capability of quickly searching e-mail headers, body text and attachments; and the ability to view multiple e-mails at the same time in separate windows and scroll through all message headers in a folder rather than one page at a time.
From the looks, the email war (think Google Gmail, Microsoft Hotmail), is heating up again.
However, I do admit that drag-and-drop feature in web based email has always been a "dream", and Yahoo! is now making that dream a reality. It would even be better if drag-and-drop can be combined with the filter/categorisation feature of Gmail.
Sooner or later, we might be even talking about themes/styles in the web-based email interface (with regards to Yahoo Mail, Gmail and Hotmail).
