After installing the plugin and setup, I added the widget to the sidebar. It was only possible to add it to one sidebar. Since the widget wasn't available anymore.
When editing the settings again, the plugin resets to defaults, it doesn't load the previous settings I saved.
When a language is selected, I can't switch the language. I selected german, and even though I chose danish afterwards. The page still was in german.
But besides that - great plugin - looking forward to a stable version :-)
