Love it or hate it, Yahoo! Mail has been redesigned once again

It's been less than a year since Yahoo's last interface redesign, and only months since their controversial logo update. Just like the previous redesign, I found myself switched to a totally new interface unexpectedly after using the 'old' look all day long.

Notable changes include:

• Conversations: the ability to group messages and replies together (optional).
• Snippets: the first few words of a message appear next to the subject line (optional).
• Page-wide themes with transparency.
• 1 TB (yes, you ready correctly) of free storage, enough for '6,000 years', according to Yahoo. 
• All features of Yahoo! Mail Plus are now free (disposable address, POP email, and mail forwarding).

• Calendar and Contacts, originally tabs above the 'Compose' button, have been moved to the sidebar.
• Folders are now hidden and require that you click the 'Folder' button to see them.
• Messenger is also hidden until the 'Messenger' button is clicked.
• When replying to a new message, 'To', 'From', and 'Subject' are now hidden by default and formatting options are at the bottom of the pane rather than the top.

Many of these features are now also available on the mobile Yahoo! Mail app for Android and iOS.

If you use Yahoo! Mail daily, the new look and feel will take some getting used to. If you're also a Gmail user, the blow will be softer since both services now share many similarities.
