Quick Locale Switcher 1.5 contains 2 new features:
1. Automatic switching, when this feature is on the QLS automatically remembers the website you switched a locale on and when you open that page the next time, the QLS will automatically switch to that locale again. It also tries to detect the language of sites itself, and switches to the language found. This feature only applies to the content locale (http accept_language header) and your spell checker dictionary.
2. The QLS displays the country flag of the currently selected locale in the statusbar, clicking on this flag will popup the menu in which you can select a different locale.
