Need improvement.
User interface is nice and on the security point of view is nice application.
The major drawback I have seen in this application is there is no downloading more than one thing at a time and at the time of downloading the application response to web surfing is very poor.
The application reloads when we want to go back to previous page.
It is very efficient is saving the pages and bookmarks.
The tabs very nicely designed.
These problems must be consider otherwise nice application.
