Opera Dragonfly beta 1

Opera has improved its Dragonfly debugging tool with the release of Opera Dragonfly beta 1. Opera Dragonfly covers the full debugging workflow, from inspecting network access and downloaded resources, to correcting JavaScript issues and seeing how CSS rules apply to the DOM. It supports all the newest web technologies, including SVG and HTML5 APIs such as Web Storage.

JavaScript debugger
Enables stepping through your code line by line, setting break points along the way.
Monitor the exact expression or specific variable in your JavaScript code.
Use the Break points panel to see exactly what caused a JavaScript fail.
Added new types of break points and more granular control.
CSS inspector
Check out what CSS rules apply to which element, and what rules are inherited or set by browser defaults.
Overridden rules are highlighted showing what styles are, or are not applied.
Use the CSS editing feature to edit existing properties and values.
Use the auto-complete feature to make editing faster and more convenient.
DOM inspector
Allows inspection of the updated DOM and all of its properties.
The DOM can be edited to experiment with changes directly in the browser.
Network inspector
Allows inspection of the HTTP request and response headers.
A summary of each request is shown, with the method type, response status and the time taken to be retrieved.
Drill down to see full details of each requests header.
Find latency, see how resources download and in what order, and even view cached resources.
Resource inspector
See all site resources such as images, scripts, fonts, HTML files and videos at a glance.
Storage inspector
Cookies and Web Storage can be dynamically updated, tested, inspected, and manipulated.
Error console
Allows you to see, filter and log any errors in your scripts, pointing to the exact position where the error occurred.
Use the Error console in combination with the other tools to hunt down and fix your site's bugs.
Debug your phone or TV
Debug pages whether they are on your computer or a supported device, such as a phone running Opera Mobile 10 for Windows Mobile.
You can connect to any device running Opera Presto 2.1 or above and debug using your computer's screen and keyboard. There is no need to struggle inputting test data with your phone's keypad again.
Opera Widgets can also be debugged via remote debugging.
Design utilities
A color picker and a screen magnifier allow you to pick out colors from a website or widget.
The average color of an area can be selected to make it easier to pick out colors from bitmap images.
Chosen colors can be stored in a palette for later access.
Open source
Built using the open web standards you know and love, Opera Dragonfly's source is available to view.
Not only that, but it is released on a Apache 2.0 license, meaning it is free as in freedom, as well as in beer.
Join in the project, or just check out the source code at the Opera Dragonfly repository.

Mail

Added support for phrase searching.
Improved CJK searches.
Improvements made to the panel, including a setting to disable automatic toggling.
Improved support when using the Opera Mail client with a Gmail IMAP account.
Opera now recognizes the special IMAP folders "Sent items", "Spam", "Trash" and treats them as equivalents of the native Sent, Spam and Trash views in Opera Mail. This also works for other IMAP servers that support the XLIST or SPECIAL-USE extensions for the IMAP specification, including the Fastmail IMAP service.
Opera now recognizes the special way in which Gmail duplicates messages that appear in the "All Mail" IMAP folder and the various folders created by Gmail's own "labels" (including Inbox). To make the best use of this, it is recommended that you subscribe to the all the Gmail IMAP folders (this is a change from earlier advice to suggested users to unsubscribe from the [Gmail]\* folders).
Opera Mail will then make sure that messages do not show up twice in its "Unread" and "Recieved" views. As for other views like "Mailing lists", "Contacts", "Labels", and "Attachments", duplication can still occur there. You can improve on this for now by unchecking "Show hidden" for such views (use the "View" button in the mail view, then "Show > Show hidden").

Search

Search hijacking protection: Opera now prevents third party applications from hijacking searches and other customizations in Opera.
Added a Search field to error pages, where the browser will make a search request over the net for suggestions and display them.

Speed Dial

Added Speed Dial animation to help when reordering (dragging and dropping) existing Speed Dial cells, using smooth visual cues.
Added a new "logo finder" which keys in on the main title of a page; diabled when "Reload every" is applied.
Improvements have been made to the Speed Dial flow layout.
Added the ability to set the number of Speed Dial columns (automatic by default).
Added a new dialog when adding/editing Speed Dials
It is now possible to add a custom title to Speed Dials, through the new add/edit dialog.
Sites can now reload Speed Dials automatically using one of two methods:
HTTP header: Preview-refresh: seconds
HTML code: <meta http-equiv="preview-refresh" content="seconds">
The Speed Dial thumbnail/icon is now determined using these criteria (in order):
Send a http header to tell the server it is a Speed Dial request
Detect big icons: <link rel=icon,apple-touch-icon ...> and display them instead of a thumbnail
Find the important part of the page (logo), and zoom in closer
Apply CSS view-mode: minimized when generating the thumbnail
Updated graphics for Speed Dial and callout dialogs
Speed Dial now has automatic zooming
Speed Dial options are instantly applied

User JavaScript

Added support for the BeforeCSS and AfterCSS events.
See: User JavaScript: Available methods, events, and properties
