Thank you for all the feedbacks, comments I received in the last 3 days, they were really very useful!
Based on your feedbacks 2 serious bugs have been already fixed, both related to importing bookmarks.
Many of you didn't like the popup message after saving the settings on the Settings page. I can totally agree, that message dialog was really irritating, I didn't like it either. The popup dialog has been removed, now a "Settings saved" message appears on the page for one second.
