* Added user interface for built-in crash reporting. Please remember to add any relevant details before sending the report (only Windows for now)
* Turbo mode is now disabled automatically for local IP addresses and hostnames
* Work on adding a placeholder image for plugins that are missing or not loaded (in Turbo mode) - see the “extras” folder for the SVG file
* Google TLD server work. On first run, we contact a Google server, and it returns the correct top level domain (TLD) to use (google.ru for Russia, google.no for Norway, and so on)
* Show sent mail when using threading in the e-mail client
* Updated Presto version to 2.2.2
* Some improvements for skin designers:
1) Added “Reload skin” action, which can be assigned to a keyboard shortcut in the shortcut editor (e.g. “F5 ctrl” - “Reload skin” under the “Application” section)
2) You can point to an unzipped skin by adding the full path to the skin.ini file in opera:config#UserPrefs|ButtonSet (use the “Reload skin” action after changing the setting)
3) Toolbar.ini defines new button skins for each toolbar, so each toolbar can be skinned separately. Fallback is Toolbar Button Skin. (Known issue: Native skins not updated yet, so they will get the hover state for the default skin instead)
