"Now, the sneak peek we definitely like -- it lets you preview a message without opening it so you can take immediate action," comments ReadWriteWeb. Nested labels, meanwhile, "turns Gmail's
once-revolutionary 'tagging' system into something that more closely resembles the traditional folder structure found in email programs like Outlook." The purported problem with Gmail's tagging system
is that there's no easy way to retrieve a combination of tags.
ReadWriteWeb, in its humble opinion, believes that Gmail has missed an opportunity to take labels to "the next level," i.e.,
"Why can't there be an easy-to-use function somewhere at the top of the inbox to filter your mail by labels? Why isn't there an email intelligence system that learns how you label your mail and then
starts auto-tagging it for you? Why can't Gmail figure out that if a particular message matches a filter you designed to label your incoming mail that means the message is not spam?" Yeah, why not?!
Your move, Google.
