Thunderbird 15 BETA 1 landed in Ubuntu 12.10 (how to use the Ubuntu One support)

Days ago, Mozilla released the first BETA in the 15 series for Thunderbird, introducing exciting fresh features, such as Ubuntu One integration (for attachments), and long-awaited user interface enhancements, like the new enabled-by-default Australis theme (especially visible on Thunderbird's toolbar).

During the landing of new releases in Ubuntu 12.10 (the at-the-moment development version), the Ubuntu developers usually publish the new Firefox and Thunderbird features "as is", meaning, if the Mozilla developers add a feature, the Ubuntu developer land the new Firefox and Thunderbird releases with that feature.

Nevertheless, there are cases, probably due to Ubuntu's branding policy, when exciting additions are ignored, as in the case of Firefox's refreshed Home Page with fancy bottom bar, from where the user can (if the mentioned feature is enabled) 1-click access download history, bookmarks, restore session, etc.

Thunderbird 15 BETA 1 has landed in Quantal Quetzal, introducing the new Australis theme, enabled by default, a definitely noticeable visual addition, that takes Thunderbird a step further towards a more modern look&feel with good-looking rounded tabs blended into the lower-part of the toolbar, creating a fancy compact appearance.

The Ubuntu One support has landed, too, in an usable state, bringing the powerful yet easy-to-use capability of housing large attachments to one's Ubuntu One account.

In order to use the Ubuntu One support in the 15 BETA 1:

• first, navigate Thunderbird-->Edit-->Preferences-->Attachments-->Add-->select Ubuntu One, action followed by typing Ubuntu One Account's email address (introducing a separate email address from the Thunderbird's used email address, supported, meaning, there is the possibility to use the email address mycustomaddress@gmail.com for Thunderbird in order to receive "regular" emails and, in the same time, adding myothercustomaddress@yahoo.com, that represents the address used for one's Ubuntu One account, to store large attachments) and the required password, action followed by the handy display of Ubuntu One's storage status directly inside Thunderbird's Attachments panel, allowing the user to accurately observe storage-specific details
  

  

• Offer to share for files larger than 1 MB is checked by default (and adjustable per user's demands), option that will summon a bottom dialog This is a large file. It might be better to use Filelink instead, when in Write a new email-->Attach and selecting a file bigger than 1MB to be used as attachment
  
• clicking Link will automatically upload the file to Ubuntu One, upload process achievable (for other attachments) by right-clicking on the attachment-->Convert to-->UbuntuOne
